 *          library. The new property list class can inherit from an
 *          existing property list class, \p parent, or may be derived
 *          from the default “empty” class, NULL. New classes with
 *          inherited properties from existing classes may not remove
 *          those existing properties, only add or remove their own class
 *          properties. Property list classes defined and supported in the
 *          HDF5 library distribution are listed and briefly described in
 *          H5Pcreate(). The \p create routine is called when a new property
 *          list of this class is being created. The #H5P_cls_create_func_t
 *          callback function is defined as follows:

 *          </table>
 *
 *          The \p create routine is called after any registered
 *          \p create function is called for each property value. If the
 *          \p create routine returns a negative value, the new list is not
 *          returned to the user and the property list creation routine returns
 *          an error value.
 *
 *          The \p copy routine is called when an existing property
 *          list of this class is copied. The #H5P_cls_copy_func_t callback

 *          </table>
 *
 *          The \p copy routine is called after any registered \p copy function
 *          is called for each property value. If the \p copy routine returns a
 *          negative value, the new list is not returned to the user and the
 *          property list \p copy routine returns an error value.
 *
 *           The \p close routine is called when a property list of this class
 *           is being closed. The #H5P_cls_close_func_t callback function is
 *           defined as follows:
 *           \snippet this H5P_cls_close_func_t_snip

 *          an error value but the property list is still closed.
 *
 *          H5Pclose_class() can be used to release the property list class

 *          </table>
 *
 *          The \p set routine may modify the value pointer to be set and
 *          those changes will be used when setting the property's value.
 *          If the \p set routine returns a negative value, the new property

 *          returns an error value. The \p set routine will be called for
 *          the initial value.
 *
 *          \b Note: The \p set callback function may be useful to range
 *          check the value being set for the property or may perform some
 *          transformation or translation of the value set. The \p get
 *          callback would then reverse the transformation or translation.

 *
 *          The \p prp_del routine is called when a property is being

 *          the property list \p prp_del routine returns an error value but

 *          is not copied into the property and the copy routine returns an
 *          error value.
 *
 *          The \p compare routine is called when a property list with this
 *          property is compared to another property list with the same
 *          property.
 *
 *          The #H5P_prp_compare_func_t callback function is defined as

 *           </tr>
 *          </table>
 *
 *          The \p compare routine may not modify the values. The \p compare
 *          routine should return a positive value if \p value1 is greater
 *          than \p value2, a negative value if \p value2 is greater than
 *          \p value1 and zero if \p value1 and \p value2 are equal.
 *
 *          The \p close routine is called when a property list with this
 *          property is being closed.
 *
 *          The #H5P_prp_close_func_t callback function is defined as follows:
 *          \snippet this H5P_prp_cb1_t_snip
 *

 *          </table>
 *

 *          property value is not copied into the property and the \p copy
 *          routine returns an error value.
 *
 *          The \p compare routine is called when a property list with this
 *          property is compared to another property list with the same
 *          property. The #H5P_prp_compare_func_t callback function is
 *          defined as follows:

 *          \p value1 and zero if \p value1 and \p value2 are equal.
 *
 *          The \p close routine is called when a property list with this
 *          property is being closed. The #H5P_prp_close_func_t callback

 *       compact, or external datasets.
 *
 * \note Dataset elements of variable-length and dataset region
 *       reference datatypes are stored in separate structures in the
 *       file called heaps. Filters cannot currently be applied to
 *       these heaps.
 *
 * \note <b>Filter Behavior in HDF5:</b><br />
 *       Filters can be inserted into the HDF5 pipeline to perform
 *       functions such as compression and conversion. As such, they are
 *       a very flexible aspect of HDF5; for example, a user-defined
 *       filter could provide encryption for an HDF5 dataset.
 *
 * \note A filter can be declared as either required or optional.
 *       Required is the default status; optional status must be
 *       explicitly declared.
 *
 * \note A required filter that fails or is not defined causes an
 *       entire output operation to fail; if it was applied when the
 *       data was written, such a filter will cause an input operation
 *       to fail.
 *
 * \note The following table summarizes required filter behavior.
 *          <table>
 *           <tr>
 *            <th></th>
 *            <th>Required FILTER_X not available</th>
 *            <th>FILTER_X available</th>
 *           </tr>
 *           <tr>
 *            <td>H5Pset_<FILTER_X></td>
 *            <td>Will fail.</td>
 *            <td>Will succeed.</td>
 *           </tr>
 *           <tr>
 *            <td>H5Dwrite with FILTER_X set</td>
 *            <td>Will fail.</td>
 *            <td>Will succeed; FILTER_X will be applied to
 *                the data.</td>

 *            <td>Will succeed.</td>
 *           </tr>
 *          </table>
 * \note An optional filter can be set for an HDF5 dataset even when
 *       the filter is not available. Such a filter can then be
 *       applied to the dataset when it becomes available on the
 *       original system or when the file containing the dataset is
 *       processed on a system on which it is available.
 *
 * \note A filter can be declared as optional through the use of the
 *       #H5Z_FLAG_OPTIONAL flag with H5Pset_filter().
 *
 * \note Consider a situation where one is creating files that will
 *       normally be used only on systems where the optional (and
 *       fictional) filter FILTER_Z is routinely available. One can
 *       create those files on system A, which lacks FILTER_Z, create
 *       chunked datasets in the files with FILTER_Z defined in the
 *       dataset creation property list, and even write data to those
 *       datasets. The dataset object header will indicate that FILTER_Z
 *       has been associated with this dataset. But since system A does
 *       not have FILTER_Z, dataset chunks will be written without it
 *       being applied.
 *
 * \note HDF5 has a mechanism for determining whether chunks are
 *       actually written with the filters specified in the object
 *       header, so while the filter remains unavailable, system A will
 *       be able to read the data. Once the file is moved to system B,
 *       where FILTER_Z is available, HDF5 will apply FILTER_Z to any
 *       data rewritten or new data written in these datasets. Dataset
 *       chunks that have been written on system B will then be
 *       unreadable on system A; chunks that have not been re-written
 *       since being written on system A will remain readable on system
 *       A. All chunks will be readable on system B.
 *
 * \note The following table summarizes optional filter behavior.
 *          <table>
 *           <tr>
 *            <th></th>
 *            <th>FILTER_Z not available</th>

 * \note The above principles apply generally in the use of HDF5
 *       optional filters insofar as HDF5 does as much as possible to
 *       complete an operation when an optional filter is unavailable.
 *       (The SZIP filter is an exception to this rule; see H5Pset_szip()

 *
 * \attention The Fletcher32 EDC checksum filter was added in HDF5 Release
 *            1.6.0. In the original implementation, however, the checksum
 *            value was calculated incorrectly on little-endian systems.
 *            The error was fixed in HDF5 Release 1.6.3.
 *
 * \attention As a result of this fix, an HDF5 library of Release 1.6.0
 *            through Release 1.6.2 cannot read a dataset created or written
 *            with Release 1.6.3 or later if the dataset was created with
 *            the checksum filter and the filter is enabled in the reading
 *            library. (Libraries of Release 1.6.3 and later understand the
 *            earlier error and compensate appropriately.)
 *
 * \attention \b Work-around: An HDF5 library of Release 1.6.2 or earlier
 *            will be able to read a dataset created or written with the
 *            checksum filter by an HDF5 library of Release 1.6.3 or later
 *            if the checksum filter is disabled for the read operation.
 *            This can be accomplished via a call to H5Pset_edc_check()
 *            with the value #H5Z_DISABLE_EDC in the second parameter.
 *            This has the obvious drawback that the application will be

 *
 *          The raw data chunk cache inserts chunks into the cache by first
 *          computing a hash value using the address of a chunk and then by
 *          using that hash value as the chunk’s index into the table of
 *          cached chunks. In other words, the size of this hash table and the
 *          number of possible hash values is determined by the \p rdcc_nslots

 *
 *      \b Motivation: Setting raw data chunk cache parameters
 *       can be done with H5Pset_cache(), H5Pset_chunk_cache(),
 *       or a combination of both. H5Pset_cache() is used to
 *       adjust the chunk cache parameters for all datasets via
 *       a global setting for the file, and H5Pset_chunk_cache()
 *       is used to adjust the chunk cache parameters for
 *       individual datasets. When both are used, parameters
 *       set with H5Pset_chunk_cache() will override any parameters
 *       set with H5Pset_cache().
 *
 * \note Optimum chunk cache parameters may vary widely depending
 *       on different data layout and access patterns. For datasets
 *       with low performance requirements for example, changing
 *       the cache settings can save memory.
 *
 * \note Note: Raw dataset chunk caching is not currently
 *       supported when using the MPI I/O and MPI POSIX file drivers
 *       in read/write mode; see H5Pset_fapl_mpio() and
 *       H5Pset_fapl_mpiposix(), respectively. When using one of these
 *       file drivers, all calls to H5Dread() and H5Dwrite() will access
 *       the disk directly, and H5Pset_cache() will have no effect on
 *       performance.
 *
 * \note Raw dataset chunk caching is supported when these drivers are
 *       used in read-only mode.
 *
 * \todo Check on H5Pset_fapl_mpio() and H5Pset_fapl_mpiposix().
 *

 *
 *          When data of the above datatype is stored on disk using the

 *          The N-Bit filter is used effectively for compressing data of
 *          an N-Bit datatype as well as a compound and an array
 *          datatype with N-Bit fields. However, the datatype classes of
 *          the N-Bit datatype or the N-Bit field of the compound
 *          datatype or the array datatype are limited to integer or
 *          floating-point.
 *
 *          The N-Bit filter supports complex situations where a compound
 *          datatype contains member(s) of a compound datatype or an array
 *          datatype that has a compound datatype as the base type.
 *          However, it does not support the situation where an array
 *          datatype has a variable-length or variable-length string as
 *          its base datatype. The filter does support the situation where
 *          a variable-length or variable-length string is a member of a

 *
 *          The N-Bit filter allows all other HDF5 datatypes (such as

 *
 * \details H5Pset_scaleoffset() sets the scale-offset filter,
 *          #H5Z_FILTER_SCALEOFFSET, for a dataset.
 *
 *          Generally speaking, scale-offset compression performs a scale and/or
 *          offset operation on each data value and truncates the resulting
 *          value to a minimum number of bits (MinBits) before storing it. The
 *          current scale-offset filter supports integer and floating-point
 *          datatypes.
 *
 *          For an integer datatype, the parameter \p scale_type should be set
 *          to #H5Z_SO_INT (2). The parameter \p scale_factor denotes MinBits.
 *          If the user sets it to H5Z_SO_INT_MINBITS_DEFAULT (0), the filter
 *          will calculate MinBits. If \p scale_factor is set to a positive
 *          integer, the filter does not do any calculation and just uses the
 *          number as MinBits. However, if the user gives a MinBits that is less
 *          than what would be generated by the filter, the compression will be
 *          lossy. Also, the MinBits supplied by the user cannot exceed the
 *          number of bits to store one value of the dataset datatype.
 *
 *          For a floating-point datatype, the filter adopts the GRiB data
 *          packing mechanism, which offers two alternate methods: E-scaling and
 *          D-scaling. Both methods are lossy compression. If the parameter
 *          \p scale_type is set to #H5Z_SO_FLOAT_DSCALE (0), the filter will
 *          use the D-scaling method; if it is set to #H5Z_SO_FLOAT_ESCALE (1),
 *          the filter will use the E-scaling method. Since only the D-scaling
 *          method is implemented, \p scale_type should be set to
 *          #H5Z_SO_FLOAT_DSCALE or 0.
 *
 *          When the D-scaling method is used, the original data is "D" scaled
 *          — multiplied by 10 to the power of \p scale_factor, and the
 *          "significant" part of the value is moved to the left of the decimal
 *          point. Care should be taken in setting the decimal \p scale_factor
 *          so that the integer part will have enough precision to contain the
 *          appropriate information of the data value. For example, if
 *          \p scale_factor is set to 2, the number 104.561 will be 10456.1
 *          after "D" scaling. The last digit 1 is not "significant" and is
 *          thrown off in the process of rounding. The user should make sure that
 *          after "D" scaling and rounding, the data values are within the range
 *          that can be represented by the integer (same size as the
 *          floating-point type).
 *
 *          Valid values for scale_type are as follows:
 *
 *          <table>
 *          <tr>
 *            <td>#H5Z_SO_FLOAT_DSCALE (0)</td>

 *            <td>Integer type</td>
 *          </tr>
 *          </table>
 *
 *          The meaning of \p scale_factor varies according to the value
 *          assigned to \p scale_type:

 *          <table>

 *
 *          Before proceeding, all users should review the “Limitations”
 *          section below.
 *
 *          Users familiar with SZIP outside the HDF5 context may benefit
 *          from reviewing the Note “For Users Familiar with SZIP in Other
 *          Contexts” below.
 *
 *          In the text below, the term pixel refers to an HDF5 data element.
 *          This terminology derives from SZIP compression's use with image
 *          data, where pixel referred to an image pixel.
 *
 *          The SZIP \p bits_per_pixel value (see Note, below) is automatically
 *          set, based on the HDF5 datatype. SZIP can be used with atomic
 *          datatypes that may have size of 8, 16, 32, or 64 bits.
 *          Specifically, a dataset with a datatype that is 8-, 16-, 32-, or
 *          64-bit signed or unsigned integer; char; or 32- or 64-bit float
 *          can be compressed with SZIP. See Note, below, for further
 *          discussion of the the SZIP \p bits_per_pixel setting.
 *
 *          SZIP options are passed in an options mask, \p options_mask,
 *          as follows.
 *
 *          <table>
 *            <tr>
 *             <th>Option</th>
 *             <th>Description (Mutually exclusive; select one.)</th>
 *            </tr>
 *            <tr>

 *            </tr>
 *            <tr>
 *             <td>#H5_SZIP_NN_OPTION_MASK</td>
 *             <td>Selects nearest neighbor coding method</td>
 *            </tr>
 *           </table>
 *
 *           The following guidelines can be used in determining which
 *           option to select:
 *
 *           - The entropy coding method, the EC option specified by
 *             #H5_SZIP_EC_OPTION_MASK, is best suited for data that has been
 *             processed. The EC method works best for small numbers.
 *           - The nearest neighbor coding method, the NN option specified
 *             by #H5_SZIP_NN_OPTION_MASK, preprocesses the data then the
 *             applies EC method as above.
 *
 *           Other factors may affect results, but the above criteria
 *           provides a good starting point for optimizing data compression.
 *
 *           SZIP compresses data block by block, with a user-tunable block
 *           size. This block size is passed in the parameter
 *           \p pixels_per_block and must be even and not greater than 32,
 *           with typical values being 8, 10, 16, or 32. This parameter
 *           affects compression ratio; the more pixel values vary, the
 *           smaller this number should be to achieve better performance.
 *
 *           In HDF5, compression can be applied only to chunked datasets.
 *           If \p pixels_per_block is bigger than the total number of
 *           elements in a dataset chunk, H5Pset_szip() will succeed but
 *           the subsequent call to H5Dcreate() will fail; the conflict
 *           can be detected only when the property list is used.
 *
 *           To achieve optimal performance for SZIP compression, it is
 *           recommended that a chunk's fastest-changing dimension be equal
 *           to N times \p pixels_per_block where N is the maximum number of
 *           blocks per scan line allowed by the SZIP library. In the
 *           current version of SZIP, N is set to 128.
 *
 *           SZIP compression is an optional HDF5 filter.
 *
 *           \b Limitations:
 *
 *           - SZIP compression cannot be applied to compound, array,
 *             variable-length, enumeration, or any other user-defined
 *             datatypes. If an SZIP filter is set in a dataset creation
 *             property list used to create a dataset containing a
 *             non-allowed datatype, the call to H5Dcreate() will fail; the
 *             conflict can be detected only when the property list is used.
 *           - Users should be aware that there are factors that affect one’s
 *             rights and ability to use SZIP compression by reviewing the
 *             SZIP copyright notice.
 *
 * \note \b For \b Users \b Familiar \b with \b SZIP \b in \b Other \b Contexts:
 *
 * \note  The following notes are of interest primarily to those who have
 *        used SZIP compression outside of the HDF5 context.
 *        In non-HDF5 applications, SZIP typically requires that the user
 *        application supply additional parameters:
 *        - \p pixels_in_object, the number of pixels in the object to
 *          be compressed
 *        - \p bits_per_pixel, the number of bits per pixel
 *        - \p pixels_per_scanline, the number of pixels per scan line
 *
 * \note  These values need not be independently supplied in the HDF5
 *        environment as they are derived from the datatype and dataspace,
 *        which are already known. In particular, HDF5 sets
 *        \p pixels_in_object to the number of elements in a chunk and
 *        \p bits_per_pixel to the size of the element or pixel datatype.
 *
 * \note  The following algorithm is used to set \p pixels_per_scanline:
 *        - If the size of a chunk's fastest-changing dimension, size,
 *          is greater than 4K, set \p pixels_per_scanline to 128 times
 *          \p pixels_per_block.
 *        - If size is less than 4K but greater than \p pixels_per_block,
 *          set \p pixels_per_scanline to the minimum of size and 128
 *          times \p pixels_per_block.
 *        - If size is less than \p pixels_per_block but greater than the
 *          number elements in the chunk, set \p pixels_per_scanline to
 *          the minimum of the number elements in the chunk and 128 times
 *          \p pixels_per_block.
 *
 * \note  The HDF5 datatype may have precision that is less than the full
 *        size of the data element, e.g., an 11-bit integer can be defined
 *        using H5Tset_precision(). To a certain extent, SZIP can take
 *        advantage of the precision of the datatype to improve compression:
 *        - If the HDF5 datatype size is 24-bit or less and the offset of
 *          the bits in the HDF5 datatype is zero (see H5Tset_offset() or
 *          H5Tget_offset()), the data is the in lowest N bits of the data
 *          element. In this case, the SZIP \p bits_per_pixel is set to the
 *          precision of the HDF5 datatype.
 *        - If the offset is not zero, the SZIP \p bits_per_pixel will be
 *          set to the number of bits in the full size of the data element.
 *        - If the HDF5 datatype precision is 25-bit to 32-bit, the SZIP
 *          \p bits_per_pixel will be set to 32.
 *        - If the HDF5 datatype precision is 33-bit to 64-bit, the SZIP
 *          \p bits_per_pixel will be set to 64.
 *
 * \note HDF5 always modifies the options mask provided by the user to set up
 *       usage of RAW_OPTION_MASK, ALLOW_K13_OPTION_MASK, and one of
 *       LSB_OPTION_MASK or MSB_OPTION_MASK, depending on endianness of the
 *       datatype.

 *          actions above are not invoked.
 *
 *          The specified boundary is indicated by the parameter
 *          \p boundary. It is a 1-dimensional array with \p ndims
 *          elements, which should be the same as the rank of the
 *          dataset’s dataspace. While appending to a dataset along a

 *          size is divisible by \p boundary[index]. A zero value for
 *          \p boundary[index] indicates no boundary is set for that
 *          dimension index.
 *
 *          The setting of this property will apply only for a chunked
 *          dataset with an extendible dataspace. A dataspace is extendible
 *          when it is defined with either one of the following:
 *
 *          \li A dataspace with fixed current and maximum dimension sizes
 *          \li A dataspace with at least one unlimited dimension for its
 *              maximum dimension size
 *
 *          When creating or opening a chunked dataset, the library will
 *          check whether the boundary as specified in the access property
 *          list is set up properly. The library will fail the dataset
 *          create or open if the following conditions are true:
 *
 *          \li \p ndims, the number of elements for boundary, is not the
 *              same as the rank of the dataset’s dataspace.
 *          \li A non-zero boundary value is specified for a non-extendible
 *          dimension.

 *          calling this function, the values set in the property list
 *          will override the values in the file's file access property
 *          list.
 *
 *          The raw data chunk cache inserts chunks into the cache
 *          by first computing a hash value using the address of a chunk,
 *          then using that hash value as the chunk's index into the table
 *          of cached chunks. The size of this hash table, i.e., and the
 *          number of possible hash values, is determined by the
 *          \p rdcc_nslots parameter. If a different chunk in the cache
 *          has the same hash value, this causes a collision, which
 *          reduces efficiency. If inserting the chunk into cache would
 *          cause the cache to be too big, then the cache is pruned
 *          according to the \p rdcc_w0 parameter.
 *
 *      \b Motivation: H5Pset_chunk_cache() is used to adjust the chunk
 *       cache parameters on a per-dataset basis, as opposed to a global
 *       setting for the file using H5Pset_cache(). The optimum chunk
 *       cache parameters may vary widely with different data layout and
 *       access patterns, so for optimal performance they must be set
 *       individually for each dataset. It may also be beneficial to
 *       reduce the size of the chunk cache for datasets whose
 *       performance is not important in order to save memory space.
 *
 *      \b Example \b Usage: The following code sets the chunk cache to
 *       use a hash table with 12421 elements and a maximum size of
 *       16 MB, while using the preemption policy specified for the
 *       entire file:
 *       \Code{
 *       H5Pset_chunk_cache(dapl_id, 12421, 16*1024*1024,
 *            H5D_CHUNK_CACHE_W0_DEFAULT);}
 *
 *      \b Usage \b Notes: The chunk cache size is a property for
 *       accessing a dataset and is not stored with a dataset or a
 *       file. To guarantee the same chunk cache settings each time
 *       the dataset is opened, call H5Dopen() with a dataset access
 *       property list where the chunk cache size is set by calling
 *       H5Pset_chunk_cache() for that property list. The property
 *       list can be used for multiple accesses in the same
 *       application.
 *
 *       For files where the same chunk cache size will be
 *       appropriate for all or most datasets, H5Pset_cache() can
 *       be called with a file access property list to set the
 *       chunk cache size for accessing all datasets in the file.
 *
 *       Both methods can be used in combination, in which case
 *       the chunk cache size set by H5Pset_cache() will apply
 *       except for specific datasets where H5Dopen() is called
 *       with dataset property list with the chunk cache size
 *       set by H5Pset_chunk_cache().
 *
 *       In the absence of any cache settings, H5Dopen() will
 *       by default create a 1 MB chunk cache for the opened
 *       dataset. If this size happens to be appropriate, no
 *       call will be needed to either function to set the
 *       chunk cache size.
 *
 *       It is also possible that a change in access pattern
 *       for later access to a dataset will change the
 *       appropriate chunk cache size.

 *          when searching for the raw data files associated with a dataset

 *
 *          \li The default behavior of the library is to search for the

 *              directory as the HDF5 file which contains the dataset.
 *          \li If the prefix is set to an absolute path, the target

 *          \p plist_id. The search as described in the next paragraph is
 *          effective only if the #H5O_COPY_MERGE_COMMITTED_DTYPE_FLAG is
 *          enabled in the object copy property list via
 *          H5Pset_copy_object().
 *
 *          When copying a committed datatype, a dataset with a committed
 *          datatype, or an object with an attribute of a committed
 *          datatype, the default behavior of H5Ocopy() is to search for
 *          a matching committed datatype:
 *          <ol>
 *          <li> First search the list of suggested paths in the object
 *               copy property list.</li>
 *          <li> Then, if no match has been found, search all the committed
 *               datatypes in the destination file.
 *          </ol>
 *          The default Step 2 in this search process can be changed by
 *          setting a callback function (see H5Pset_mcdt_search_cb()).
 *
 *          Two datatypes are determined equal if their descriptions are
 *          identical, in a manner similar to H5Tequal(). If either
 *          committed datatype has one or more attributes, then all
 *          attributes must be present in both committed datatypes and they
 *          must be identical. Two attributes are considered identical if
 *          their datatype description, dataspace, and raw data values are
 *          the same. However, if an attribute uses a committed datatype,
 *          that committed datatype’s attributes will not be compared.
 *
 *          If a match is found, H5Ocopy() will perform the following in
 *          the destination file:
 *          \li For a committed datatype, the library will create a hard
 *              link to the found datatype.
 *          \li For a dataset that uses a committed datatype, the library
 *              will modify the copied dataset to use the found committed
 *              datatype as its datatype.
 *          \li For an object with an attribute of a committed datatype,
 *              the library will modify the copied object’s attribute to
 *              use the found committed datatype as its datatype.
 *
 *          If no match is found, H5Ocopy() will perform the following in
 *          the destination file:
 *          \li For a committed datatype, the library will copy it as it
 *              would any other object, creating a named committed
 *              datatype at the destination. That is, the library will
 *              create a committed datatype that is accessible in the
 *              file by a unique path.
 *          \li For a dataset that uses a committed datatype, the
 *              library will copy the datatype as an anonymous
 *              committed datatype and use that as the dataset’s
 *              datatype.
 *          \li For an object with an attribute of a committed datatype,
 *              the library will copy the datatype as an anonymous
 *              committed datatype and use that as the attribute’s
 *              datatype.
 *
 *      \b Motivation: H5Padd_merge_committed_dtype_path() provides a
 *       means to override the default behavior of H5Ocopy() when
 *       #H5O_COPY_MERGE_COMMITTED_DTYPE_FLAG is set in an object
 *       copy property list.
 *       H5Padd_merge_committed_dtype_path() is the mechanism for
 *       suggesting search paths where H5Ocopy() will look for a
 *       matching committed datatype. This can be substantially
 *       faster than the default approach of searching the entire
 *       destination file for a match.
 *
 *       \b Example \b Usage: This example adds two paths to the object
 *          copy property list. H5Ocopy() will search the two suggested
 *          paths for a match before searching all the committed datatypes
 *          in the destination file.

 *          datatype. The default, global search process is described in
 *          H5Padd_merge_committed_dtype_path().
 *
 *          The callback function must conform to the #H5O_mcdt_search_cb_t

 *
 *       \b Motivation: H5Pset_mcdt_search_cb() provides the means to
