Introduction</h2> - - <p>HDF5 files are composed of a <em>super block</em> describing information - required to portably access files on multiple platforms, followed - by information about the groups in a file and the datasets in the - file. The super block contains information about the size of offsets - and lengths of objects, the number of entries in symbol tables - (used to store groups) and additional version information for the - file. - - <h2>2. File access modes</h2> - - <p>The HDF5 library assumes that all files are implicitly opened for read - access at all times. Passing the <code>H5F_ACC_RDWR</code> - parameter to <code>H5Fopen()</code> allows write access to a - file also. <code>H5Fcreate()</code> assumes write access as - well as read access, passing <code>H5F_ACC_TRUNC</code> forces - the truncation of an existing file, otherwise H5Fcreate will - fail to overwrite an existing file. - - <h2>3. Creating, Opening, and Closing Files</h2> - - <p>Files are created with the <code>H5Fcreate()</code> function, - and existing files can be accessed with <code>H5Fopen()</code>. Both - functions return an object ID which should be eventually released by - calling <code>H5Fclose()</code>. - - <dl> - <dt><code>hid_t H5Fcreate (const char *<em>name</em>, uintn - <em>flags</em>, hid_t <em>create_properties</em>, hid_t - <em>access_properties</em>)</code> - <dd>This function creates a new file with the specified name in - the current directory. The file is opened with read and write - permission, and if the <code>H5F_ACC_TRUNC</code> flag is set, - any current file is truncated when the new file is created. - If a file of the same name exists and the - <code>H5F_ACC_TRUNC</code> flag is not set (or the - <code>H5F_ACC_EXCL</code> bit is set), this function will - fail. Passing <code>H5P_DEFAULT</code> for the creation - and/or access property lists uses the library's default - values for those properties. Creating and changing the - values of a property list is documented further below. The - return value is an ID for the open file and it should be - closed by calling <code>H5Fclose()</code> when it's no longer - needed. A negative value is returned for failure. - - <br><br> - <dt><code>hid_t H5Fopen (const char *<em>name</em>, uintn - <em>flags</em>, hid_t <em>access_properties</em>)</code> - <dd>This function opens an existing file with read permission - and write permission if the <code>H5F_ACC_RDWR</code> flag is - set. The <em>access_properties</em> is a file access property - list ID or <code>H5P_DEFAULT</code> for the default I/O access - parameters. Creating and changing the parameters for access - property lists is documented further below. Files which are opened - more than once return a unique identifier for each - <code>H5Fopen()</code> call and can be accessed through all - file IDs. The return value is an ID for the open file and it - should be closed by calling <code>H5Fclose()</code> when it's - no longer needed. A negative value is returned for failure. - - <br><br> - <dt><code>herr_t H5Fclose (hid_t <em>file_id</em>)</code> - <dd>This function releases resources used by a file which was - opened by <code>H5Fcreate()</code> or <code>H5Fopen()</code>. After - closing a file the <em>file_id</em> should not be used again. This - function returns zero for success or a negative value for failure. - - <br><br> - <dt><code>herr_t H5Fflush (hid_t <em>object_id</em>, - H5F_scope_t <em>scope</em>)</code> - <dd>This function will cause all buffers associated with a file - to be immediately flushed to the file. The <em>object_id</em> - can be any object which is associated with a file, including - the file itself. <em>scope</em> specifies whether the flushing - action is to be global or local. - </dl> - - <h2>4. File Property Lists</h2> - - <p>Additional parameters to <code>H5Fcreate()</code> or - <code>H5Fopen()</code> are passed through property list - objects, which are created with the <code>H5Pcreate()</code> - function. These objects allow many parameters of a file's - creation or access to be changed from the default values. - Property lists are used as a portable and extensible method of - modifying multiple parameter values with simple API functions. - There are two kinds of file-related property lists, - namely file creation properties and file access properties. - - <h3>4.1. File Creation Properties</h3> - - <P>File creation property lists apply to <code>H5Fcreate()</code> only - and are used to control the file meta-data which is maintained - in the super block of the file. The parameters which can be - modified are: - - <dl> - <dt>User-Block Size <dd>The <em>user-block</em> is a fixed length block of - data located at the beginning of the file which is ignored by the - HDF5 library and may be used to store any data information found - to be useful to applications. This value may be set to any power - of two equal to 512 or greater (i.e. 512, 1024, 2048, etc). This - parameter is set and queried with the - <code>H5Pset_userblock()</code> and - <code>H5Pget_userblock()</code> calls. - - <br><br> - <dt>Offset and Length Sizes - <dd>The number of bytes used to store the offset and length of - objects in the HDF5 file can be controlled with this - parameter. Values of 2, 4 and 8 bytes are currently - supported to allow 16-bit, 32-bit and 64-bit files to - be addressed. These parameters are set and queried - with the <code>H5Pset_sizes()</code> and - <code>H5Pget_sizes()</code> calls. - - <br><br> - <dt>Symbol Table Parameters - <dd>The size of symbol table B-trees can be controlled by setting - the 1/2 rank and 1/2 node size parameters of the B-tree. These - parameters are set and queried with the - <code>H5Pset_sym_k()</code> and <code>H5Pget_sym_k()</code> calls. - - <br><br> - <dt>Indexed Storage Parameters - <dd>The size of indexed storage B-trees can be controlled by - setting the 1/2 rank and 1/2 node size parameters of the B-tree. - These parameters are set and queried with the - <code>H5Pset_istore_k()</code> and <code>H5Pget_istore_k()</code> - calls. - </dl> - - <h3>4.2. File Access Property Lists</h3> - - <p>File access property lists apply to <code>H5Fcreate()</code> or - <code>H5Fopen()</code> and are used to control different methods of - performing I/O on files. - - <dl> - <dt>Unbuffered I/O - <dd>Local permanent files can be accessed with the functions described - in Section 2 of the Posix manual, namely <code>open()</code>, - <code>lseek()</code>, <code>read()</code>, <code>write()</code>, and - <code>close()</code>. The <code>lseek64()</code> function is used - on operating systems that support it. This driver is enabled and - configured with <code>H5Pset_fapl_sec2()</code>. - - <br><br> - <dt>Buffered I/O - <dd>Local permanent files can be accessed with the functions declared - in the standard C header file <code>stdio.h</code>, namely - <code>fopen()</code>, <code>fseek()</code>, <code>fread()</code>, - <code>fwrite()</code>, and <code>fclose()</code>. The - <code>fseek64()</code> function is used on operating systems that - support it. This driver is enabled and configured with - <code>H5Pset_fapl_stdio()</code>. - - <br><br> - <dt>Memory I/O - <dd>Local temporary files can be created and accessed directly from - memory without ever creating permanent storage. The library uses - <code>malloc()</code> and <code>free()</code> to create storage - space for the file. The total size of the file must be small enough - to fit in virtual memory. The name supplied to - <code>H5Fcreate()</code> is irrelevant, and <code>H5Fopen()</code> - will always fail. - - <br><br> - <dt>Parallel Files using MPI I/O - <dd>This driver allows parallel access to a file through the MPI I/O - library. The parameters which can be modified are the MPI - communicator, the info object, and the access mode. - The communicator and info object are saved and then - passed to <code>MPI_File_open()</code> during file creation or open. - The access_mode controls the kind of parallel access the application - intends. (Note that it is likely that the next API revision will - remove the access_mode parameter and have access control specified - via the raw data transfer property list of <code>H5Dread()</code> - and <code>H5Dwrite()</code>.) These parameters are set and queried - with the <code>H5Pset_fapl_mpi()</code> and - <code>H5Pget_fapl_mpi()</code> calls. - - <br><br> - <dt>Data Alignment - <dd>Sometimes file access is faster if certain things are - aligned on file blocks. This can be controlled by setting - alignment properties of a file access property list with the - <code>H5Pset_alignment()</code> function. Any allocation - request at least as large as some threshold will be aligned on - an address which is a multiple of some number. - </dl> </ul> - - <h2>5. Examples of using file property lists</h2> - - <h3>5.1. Example of using file creation property lists</h3> - - <p>This following example shows how to create a file with 64-bit object - offsets and lengths:<br> - <pre> - hid_t create_plist; - hid_t file_id; - - create_plist = H5Pcreate(H5P_FILE_CREATE); - H5Pset_sizes(create_plist, 8, 8); - - file_id = H5Fcreate("test.h5", H5F_ACC_TRUNC, - create_plist, H5P_DEFAULT); - . - . - . - H5Fclose(file_id); - </pre> - - <h3>5.2. Example of using file creation plist</h3> - - <p>This following example shows how to open an existing file for - independent datasets access by MPI parallel I/O:<br> - <pre> - hid_t access_plist; - hid_t file_id; - - access_plist = H5Pcreate(H5P_FILE_ACCESS); - H5Pset_fapl_mpi(access_plist, MPI_COMM_WORLD, MPI_INFO_NULL); - - /* H5Fopen must be called collectively */ - file_id = H5Fopen("test.h5", H5F_ACC_RDWR, access_plist); - . - . - . - /* H5Fclose must be called collectively */ - H5Fclose(file_id); - </pre> - - - <h2>6. Low-level File Drivers</h2> - - <p>HDF5 is able to access its address space through various types of - low-level <em>file drivers</em>. For instance, an address space might - correspond to a single file on a Unix file system, multiple files on a - Unix file system, multiple files on a parallel file system, or a block - of memory within the application. Generally, an HDF5 address space is - referred to as an <em>HDF5 file</em> regardless of how the space is organized - at the storage level. - - <h3>6.1. Unbuffered Permanent Files</h3> - - <p>The <em>sec2</em> driver uses functions from section 2 of the - Posix manual to access files stored on a local file system. These are - the <code>open()</code>, <code>close()</code>, <code>read()</code>, - <code>write()</code>, and <code>lseek()</code> functions. If the - operating system supports <code>lseek64()</code> then it is used instead - of <code>lseek()</code>. The library buffers meta data regardless of - the low-level driver, but using this driver prevents data from being - buffered again by the lowest layers of the HDF5 library. - - <dl> - <dt><code>hid_t H5Pget_driver (hid_t <em>access_properties</em>)</code> - <dd>This function returns the constant <code>H5FD_SEC2</code> if the - <em>sec2</em> driver is defined as the low-level driver for the - specified access property list. - - <br><br> - <dt><code>herr_t H5Pset_fapl_sec2 - (hid_t <em>access_properties</em>)</code> - <dd>The file access properties are set to use the <em>sec2</em> - driver. Any previously defined driver properties are erased from the - property list. Additional parameters may be added to this function in - the future. - - </dl> - - <h3>6.2. Buffered Permanent Files</h3> - - <p>The <em>stdio</em> driver uses the functions declared in the - <code>stdio.h</code> header file to access permanent files in a local - file system. These are the <code>fopen()</code>, <code>fclose()</code>, - <code>fread()</code>, <code>fwrite()</code>, and <code>fseek()</code> - functions. If the operating system supports <code>fseek64()</code> then - it is used instead of <code>fseek()</code>. Use of this driver - introduces an additional layer of buffering beneath the HDF5 library. - - <dl> - <dt><code>hid_t H5Pget_driver(hid_t <em>access_properties</em>)</code> - <dd>This function returns the constant <code>H5FD_STDIO</code> if the - <em>stdio</em> driver is defined as the low-level driver for the - specified access property list. - - <br><br> - <dt><code>herr_t H5Pset_fapl_stdio - (hid_t <em>access_properties</em>)</code> - <dd>The file access properties are set to use the <em>stdio</em> - driver. Any previously defined driver properties are erased from the - property list. Additional parameters may be added to this function in - the future. - - </dl> - - <h3>6.3. Buffered Temporary Files</h3> - - <p>The <em>core</em> driver uses <code>malloc()</code> and - <code>free()</code> to allocate space for a file in the heap. Reading - and writing to a file of this type results in mem-to-mem copies instead - of disk I/O and as a result is somewhat faster. However, the total file - size must not exceed the amount of available virtual memory, and only - one HDF5 file handle can access the file (because the name of such a - file is insignificant and <code>H5Fopen()</code> always fails). - - <dl> - <dt><code>hid_t H5Pget_driver (hid_t <em>access_properties</em>)</code> - <dd>This function returns the constant <code>H5FD_CORE</code> if the - <em>core</em> driver is defined as the low-level driver for the - specified access property list. - - <br><br> - <dt><code>herr_t H5Pset_fapl_core (hid_t <em>access_properties</em>, - size_t <em>block_size</em>, - hbool_t <em>backing_store</em>)</code> - <dd>The file access properties are set to use the <em>core</em> - driver and any previously defined driver properties are erased from - the property list. Memory for the file will always be allocated in - units of the specified <em>block_size</em>. Additional parameters may - be added to this function in the future. - - <br><br> - <dt><code>herr_t H5Pget_fapl_core (hid_t <em>access_properties</em>, - size_t *<em>block_size</em>), - hbool_t *<em>backing_store</em>)</code> - <dd>If the file access property list is set to the <em>core</em> driver - then this function returns zero and <em>block_size</em> is set to the - block size used for the file; otherwise it returns a negative - value. In the future, additional arguments may be added to this - function to match those added to <code>H5Pset_fapl_core()</code>. - </dl> - - <h3>6.4. Parallel Files</h3> - - <p>This driver uses MPI I/O to provide parallel access to a file. - - <dl> - <dt><code>hid_t H5Pget_driver (hid_t <em>access_properties</em>)</code> - <dd>This function returns the constant <code>H5FD_MPI</code> if the - <em>mpi</em> driver is defined as the low-level driver for the - specified access property list. - - <br><br> - <dt><code>herr_t H5Pset_fapl_mpi (hid_t <em>access_properties</em>, MPI_Comm - <em>comm</em>, MPI_info <em>info</em>)</code> - <dd>The file access properties are set to use the <em>mpi</em> - driver and any previously defined driver properties are erased from - the property list. Additional parameters may be added to this - function in the future. - - <br><br> - <dt><code>herr_t H5Pget_fapl_mpi - (hid_t <em>access_properties</em>, - MPI_Comm *<em>comm</em>, - MPI_info *<em>info</em>)</code> - <dd>If the file access property list is set to the <em>mpi</em> driver - then this function returns zero and <em>comm</em>, and <em>info</em> - are set to the values stored in the property - list; otherwise the function returns a negative value. In the future, - additional arguments may be added to this function to match those - added to <code>H5Pset_fapl_mpi()</code>. - </dl> - - <a name="Files_Families"> - <h3>6.5. File Families</h3> - </a> - - <p>A single HDF5 address space may be split into multiple files which, - together, form a file family. Each member of the family must be the - same logical size although the size and disk storage reported by - <code>ls</code>(1) may be substantially smaller. The name passed to - <code>H5Fcreate()</code> or <code>H5Fopen()</code> should include a - <code>printf(3c)</code> style integer format specifier which will be - replaced with the family member number (the first family member is - zero). - - <p>Any HDF5 file can be split into a family of files by running - the file through <code>split</code>(1) and numbering the output - files. However, because HDF5 is lazy about extending the size - of family members, a valid file cannot generally be created by - concatenation of the family members. Additionally, - <code>split</code> and <code>cat</code> don't attempt to - generate files with holes. The <code>h5repart</code> program - can be used to repartition an HDF5 file or family into another - file or family and preserves holes in the files. - - <dl> - <dt><code>h5repart</code> [<code>-v</code>] [<code>-b</code> - <em>block_size</em>[<em>suffix</em>]] [<code>-m</code> - <em>member_size</em>[<em>suffix</em>]] <em>source - destination</em> - <dd>This program repartitions an HDF5 file by copying the source - file or family to the destination file or family preserving - holes in the underlying Unix files. Families are used for the - source and/or destination if the name includes a - <code>printf</code>-style integer format such as "%d". The - <code>-v</code> switch prints input and output file names on - the standard error stream for progress monitoring, - <code>-b</code> sets the I/O block size (the default is 1kB), - and <code>-m</code> sets the output member size if the - destination is a family name (the default is 1GB). The block - and member sizes may be suffixed with the letters - <code>g</code>, <code>m</code>, or <code>k</code> for GB, MB, - or kB respectively. - - <br><br> - <dt><code>hid_t H5Pget_driver (hid_t <em>access_properties</em>)</code> - <dd>This function returns the constant <code>H5FD_FAMILY</code> if - the <em>family</em> driver is defined as the low-level driver for the - specified access property list. - - <br><br> - <dt><code>herr_t H5Pset_fapl_family (hid_t <em>access_properties</em>, - hsize_t <em>memb_size</em>, hid_t <em>member_properties</em>)</code> - <dd>The file access properties are set to use the <em>family</em> - driver and any previously defined driver properties are erased - from the property list. Each member of the file family will - use <em>member_properties</em> as its file access property - list. The <em>memb_size</em> argument gives the logical size - in bytes of each family member but the actual size could be - smaller depending on whether the file contains holes. The - member size is only used when creating a new file or - truncating an existing file; otherwise the member size comes - from the size of the first member of the family being - opened. Note: if the size of the <code>off_t</code> type is - four bytes then the maximum family member size is usually - 2^31-1 because the byte at offset 2,147,483,647 is generally - inaccessible. Additional parameters may be added to this - function in the future. - - <br><br> - <dt><code>herr_t H5Pget_fapl_family (hid_t <em>access_properties</em>, - hsize_t *<em>memb_size</em>, - hid_t *<em>member_properties</em>)</code> - <dd>If the file access property list is set to the <em>family</em> - driver then this function returns zero; otherwise the function - returns a negative value. On successful return, - <em>access_properties</em> will point to a copy of the member - access property list which should be closed by calling - <code>H5Pclose()</code> when the application is finished with - it. If <em>memb_size</em> is non-null then it will contain - the logical size in bytes of each family member. In the - future, additional arguments may be added to this function to - match those added to <code>H5Pset_fapl_family()</code>. - </dl> - - <h3>6.6. Split Meta/Raw Files</h3> - - <p>On occasion, it might be useful to separate meta data from raw - data. The <em>split</em> driver does this by creating two files: one for - meta data and another for raw data. The application provides a base - file name to <code>H5Fcreate()</code> or <code>H5Fopen()</code> and this - driver appends a file extension which defaults to <code>.meta</code> for - the meta data file and <code>.raw</code> for the raw data file. - Each file can have its own - file access property list which allows, for instance, a split file with - meta data stored with the <em>core</em> driver and raw data stored with - the <em>sec2</em> driver. - - <dl> - <dt><code>hid_t H5Pget_driver (hid_t <em>access_properties</em>)</code> - <dd>This function returns the constant <code>H5FD_SPLIT</code> if - the <em>split</em> driver is defined as the low-level driver for the - specified access property list. - - <br><br> - <dt><code>herr_t H5Pset_fapl_split (hid_t <em>access_properties</em>, - const char *<em>meta_extension</em>, - hid_t <em>meta_properties</em>, const char *<em>raw_extension</em>, - hid_t <em>raw_properties</em>)</code> - <dd>The file access properties are set to use the <em>split</em> - driver and any previously defined driver properties are erased from - the property list. The meta file will have a name which is formed by - adding <em>meta_extension</em> (or <code>.meta</code>) to the end of - the base name and will be accessed according to the - <em>meta_properties</em>. The raw file will have a name which is - formed by appending <em>raw_extension</em> (or <code>.raw</code>) to the base - name and will be accessed according to the <em>raw_properties</em>. - Additional parameters may be added to this function in the future. - - </dl> - - -<!-- #BeginLibraryItem "/ed_libs/NavBar_UG.lbi" --><hr> -<center> -<table border=0 width=98%> -<tr><td valign=top align=left> - <a href="index.html">HDF5 documents and links</a> <br> - <a href="H5.intro.html">Introduction to HDF5</a> <br> - <a href="RM_H5Front.html">HDF5 Reference Manual</a> <br> - <a href="http://hdf.ncsa.uiuc.edu/HDF5/doc/UG/index.html">HDF5 User's Guide for Release 1.6</a> <br> - <!-- - <a href="Glossary.html">Glossary</a><br> - --> -</td> -<td valign=top align=right> - And in this document, the - <a href="H5.user.html"><strong>HDF5 User's Guide from Release 1.4.5:</strong></a> - <br> - <a href="Files.html">Files</a> - <a href="Datasets.html">Datasets</a> - <a href="Datatypes.html">Datatypes</a> - <a href="Dataspaces.html">Dataspaces</a> - <a href="Groups.html">Groups</a> - <br> - <a href="References.html">References</a> - <a href="Attributes.html">Attributes</a> - <a href="Properties.html">Property Lists</a> - <a href="Errors.html">Error Handling</a> - <br> - <a href="Filters.html">Filters</a> - <a href="Caching.html">Caching</a> - <a href="Chunking.html">Chunking</a> - <a href="MountingFiles.html">Mounting Files</a> - <br> - <a href="Performance.html">Performance</a> - <a href="Debugging.html">Debugging</a> - <a href="Environment.html">Environment</a> - <a href="ddl.html">DDL</a> -</td></tr> -</table> -</center> -<hr> -<!-- #EndLibraryItem --><!-- #BeginLibraryItem "/ed_libs/Footer.lbi" --><address> -<a href="mailto:hdfhelp@ncsa.uiuc.edu">HDF Help Desk</a> -<br> -Describes HDF5 Release 1.4.5, February 2003 -</address><!-- #EndLibraryItem --><!-- Created: Tue Jan 27 09:11:27 EST 1998 --> -<!-- hhmts start --> -Last modified: 26 April 2001 -<!-- hhmts end --> - -</body> -</html> |
