Motivation: H5P_GET_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.
Recommended Reading: This function is part of the file image operations feature set. It is highly recommended to study the guide HDF5 File Image Operations before using this feature set. See the “See Also” section below for links to other elements of HDF5 file image operations.
Upon the successful return of H5P_SET_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 H5P_SET_FILE_IMAGE_CALLBACKS call for the file access property list fapl_id.
