- *
- * H5F_ACC_RDWR: Open with read/write access. If the file is

- * implies read-only access.
- *
- * H5F_ACC_CREAT: Create a new file if it doesn't exist yet.
- * The permissions are 0666 bit-wise AND with
- * the current umask. H5F_ACC_WRITE must also
- * be specified.
- *
- * H5F_ACC_EXCL: This flag causes H5F_open() to fail if the
- * file already exists.
- *
- * H5F_ACC_TRUNC: The file is truncated and a new HDF5 superblock
- * is written. This operation will fail if the
- * file is already open.
- *
- * Unlinking the file name from the group directed graph while
- * the file is opened causes the file to continue to exist but
- * one will not be able to upgrade the file from read-only
- * access to read-write access by reopening it. Disk resources
- * for the file are released when all handles to the file are
- * closed. NOTE: This paragraph probably only applies to Unix;
- * deleting the file name in other OS's has undefined results.
- *
- * The CREATE_PARMS argument is optional. A null pointer will
- * cause the default file creation parameters to be used.
- *
- * The ACCESS_PARMS argument is optional. A null pointer will
- * cause the default file access parameters to be used.
- *
- * Return: Success: A new file pointer.

+ *
+ * H5F_ACC_RDWR: Open with read/write access. If the file is

+ * implies read-only access.
+ *
+ * H5F_ACC_CREAT: Create a new file if it doesn't exist yet.
+ * The permissions are 0666 bit-wise AND with
+ * the current umask. H5F_ACC_WRITE must also
+ * be specified.
+ *
+ * H5F_ACC_EXCL: This flag causes H5F_open() to fail if the
+ * file already exists.
+ *
+ * H5F_ACC_TRUNC: The file is truncated and a new HDF5 superblock
+ * is written. This operation will fail if the
+ * file is already open.
+ *
+ * Unlinking the file name from the group directed graph while
+ * the file is opened causes the file to continue to exist but
+ * one will not be able to upgrade the file from read-only
+ * access to read-write access by reopening it. Disk resources
+ * for the file are released when all handles to the file are
