- * Function: H5Gcopy
- *
- * Purpose: Copy an object (group or dataset) to destination location
- * within a file or cross files. PLIST_ID is a property list
- * which is used to pass user options and properties to the
- * copy. The name, dst_name, must not already be taken by some
- * other object in the destination group.
- *
- * H5Gcopy() will fail if the name of the destination object
- * exists in the destination group. For example,
- * H5Gcopy(fid_src, "/dset", fid_dst, "/dset", ...)
- * will fail if "/dset" exists in the destination file
- *
- * OPTIONS THAT HAVE BEEN IMPLEMENTED.
- * H5G_COPY_SHALLOW_HIERARCHY_FLAG
- * If this flag is specified, only immediate members of
- * the group are copied. Otherwise (default), it will
- * recursively copy all objects below the group
- * H5G_COPY_EXPAND_SOFT_LINK_FLAG
- * If this flag is specified, it will copy the objects
- * pointed by the soft links. Otherwise (default), it
- * will copy the soft link as they are
- * H5G_COPY_WITHOUT_ATTR_FLAG
- * If this flag is specified, it will copy object without
- * copying attributes. Otherwise (default), it will
- * copy object along with all its attributes
- * H5G_COPY_EXPAND_REFERENCE_FLAG
- * 1) Copy object between two different files:
- * When this flag is specified, it will copy objects that
- * are pointed by the references and update the values of
- * references in the destination file. Otherwise (default)
- * the values of references in the destination will set to
- * zero
- * The current implementation does not handle references
- * inside of other datatype structure. For example, if
- * a member of compound datatype is reference, H5Gcopy()
- * will copy that field as it is. It will not set the
- * value to zero as default is used nor copy the object
- * pointed by that field the flag is set
- * 2) Copy object within the same file:
- * This flag does not have any effect to the H5Gcopy().
- * Datasets or attributes of references are copied as they
- * are, i.e. values of references of the destination object
- * are the same as the values of the source object
- *
- * OPTIONS THAT MAY APPLY TO COPY IN THE FUTURE.
- * H5G_COPY_EXPAND_EXT_LINK_FLAG
- * If this flag is specified, it will expand the external links
- * into new objects, Otherwise (default), it will keep external
- * links as they are (default)
- *
- * PROPERTIES THAT MAY APPLY TO COPY IN FUTURE
- * Change data layout such as chunk size
- * Add filter such as data compression.
- * Add an attribute to the copied object(s) that say the date/time
- * for the copy or other information about the source file.
- *
- * The intermediate group creation property should be passed in
- * using the lcpl instead of the ocpypl.
- *
- * Usage: H5Gcopy(src_loc_id, src_name, dst_loc_id, dst_name, ocpypl_id, lcpl_id)
- * hid_t src_loc_id IN: Source file or group identifier.
- * const char *src_name IN: Name of the source object to be copied
- * hid_t dst_loc_id IN: Destination file or group identifier
- * const char *dst_name IN: Name of the destination object
- * hid_t ocpypl_id IN: Properties which apply to the copy
- * hid_t lcpl_id IN: Properties which apply to the new hard link
- *
- *
- * Return: Non-negative on success/Negative on failure

+ * Function: H5Ocopy
+ *
+ * Purpose: Copy an object (group or dataset) to destination location
+ * within a file or cross files. PLIST_ID is a property list
+ * which is used to pass user options and properties to the
+ * copy. The name, dst_name, must not already be taken by some
+ * other object in the destination group.
+ *
+ * H5Ocopy() will fail if the name of the destination object
+ * exists in the destination group. For example,
+ * H5Ocopy(fid_src, "/dset", fid_dst, "/dset", ...)
+ * will fail if "/dset" exists in the destination file
+ *
+ * OPTIONS THAT HAVE BEEN IMPLEMENTED.
+ * H5O_COPY_SHALLOW_HIERARCHY_FLAG
+ * If this flag is specified, only immediate members of
+ * the group are copied. Otherwise (default), it will
+ * recursively copy all objects below the group
+ * H5O_COPY_EXPAND_SOFT_LINK_FLAG
+ * If this flag is specified, it will copy the objects
+ * pointed by the soft links. Otherwise (default), it
+ * will copy the soft link as they are
+ * H5O_COPY_WITHOUT_ATTR_FLAG
+ * If this flag is specified, it will copy object without
+ * copying attributes. Otherwise (default), it will
+ * copy object along with all its attributes
+ * H5O_COPY_EXPAND_REFERENCE_FLAG
+ * 1) Copy object between two different files:
+ * When this flag is specified, it will copy objects that
+ * are pointed by the references and update the values of
+ * references in the destination file. Otherwise (default)
+ * the values of references in the destination will set to
+ * zero
+ * The current implementation does not handle references
+ * inside of other datatype structure. For example, if
+ * a member of compound datatype is reference, H5Ocopy()
+ * will copy that field as it is. It will not set the
+ * value to zero as default is used nor copy the object
+ * pointed by that field the flag is set
+ * 2) Copy object within the same file:
+ * This flag does not have any effect to the H5Ocopy().
+ * Datasets or attributes of references are copied as they
+ * are, i.e. values of references of the destination object
+ * are the same as the values of the source object
+ *
+ * OPTIONS THAT MAY APPLY TO COPY IN THE FUTURE.
+ * H5O_COPY_EXPAND_EXT_LINK_FLAG
+ * If this flag is specified, it will expand the external links
+ * into new objects, Otherwise (default), it will keep external
+ * links as they are (default)
+ *
+ * PROPERTIES THAT MAY APPLY TO COPY IN FUTURE
+ * Change data layout such as chunk size
+ * Add filter such as data compression.
+ * Add an attribute to the copied object(s) that say the date/time
+ * for the copy or other information about the source file.
+ *
+ * The intermediate group creation property should be passed in
+ * using the lcpl instead of the ocpypl.
+ *
+ * Usage: H5Ocopy(src_loc_id, src_name, dst_loc_id, dst_name, ocpypl_id, lcpl_id)
+ * hid_t src_loc_id IN: Source file or group identifier.
+ * const char *src_name IN: Name of the source object to be copied
+ * hid_t dst_loc_id IN: Destination file or group identifier
+ * const char *dst_name IN: Name of the destination object
+ * hid_t ocpypl_id IN: Properties which apply to the copy
+ * hid_t lcpl_id IN: Properties which apply to the new hard link
+ *
+ *
+ * Return: Non-negative on success/Negative on failure
+ *
+ * Programmer: Peter Cao
