H5F_GET_VFD_HANDLE

Returns pointer to the file handle from the virtual file driver.

Procedure:

H5F_GET_VFD_HANDLE(file_id, fapl_id, file_handle)

Signature:

herr_t H5Fget_vfd_handle(hid_t file_id, hid_t fapl_id, void **file_handle )

Parameters:
hid_t file_idIN: Identifier of the file to be queried.
hid_t fapl_idIN: File access property list identifier. For most drivers, the value will be H5P_DEFAULT. For the FAMILY or MULTI drivers, this value should be defined through the property list functions: H5Pset_family_offset for the FAMILY driver and H5Pset_multi_type for theMULTI driver.
void **file_handle    OUT: Pointer to the file handle being used by the low-level virtual file driver.

Description:

Given the file identifier file_id and the file access property list fapl_idH5Fget_vfd_handle returns a pointer to the file handle from the low-level file driver currently being used by the HDF5 library for file I/O.

Returns:

Returns a non-negative value if successful; otherwise returns a negative value.

    int         rdata[DIM0][DIM1];          /* buffer for read */
 
    hid_t       file_id, dataset_id;        /* handles */
