H5Pget_file_image_callbacks
(
hid_t fapl_id
,
H5_file_image_callbacks_t *callbacks_ptr
)
H5Pget_file_image_callbacks
and other elements of HDF5 are
used to load an image of an HDF5 file into system memory and open
that image as a regular HDF5 file.
An application can then use the file without the overhead of disk I/O.
See the “See Also” section below for links to other elements of HDF5 file image operations.
H5Pget_file_image_callbacks
retrieves the callback routines set for working with file images
opened with the file access property list fapl_id
.
The callbacks must have been previously set with
H5Pset_file_image_callbacks
in the file access property list.
Upon the successful return of H5Pget_file_image_callbacks
,
the fields in the instance of the H5_file_image_callbacks_t
struct pointed to by callbacks_ptr
will contain the same
values as were passed in the most recent
H5Pset_file_image_callbacks
call for the
file access property list fapl_id
.
hid_t fapl_id
| IN: File access property list identifier. | |
H5_file_image_callbacks_t *callbacks_ptr
| ||
IN/OUT: Pointer to the instance of the
H5_file_image_callbacks_t struct
in which the callback routines are to be returned.
Struct fields must be initialized to
Struct field contents upon return will match those
passed in in the last
