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_id | IN: Identifier of the file to be queried. |
hid_t fapl_id | IN: 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_id, H5Fget_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.
Example:
int
main (void)
{
hsize_t dims[2], dimsm[2];
int data[DIM0][DIM1]; /* data to write */
int sdata[DIM0_SUB][DIM1_SUB]; /* subset to write */
int rdata[DIM0][DIM1]; /* buffer for read */
hid_t file_id, dataset_id; /* handles */
hid_t dataspace_id, memspace_id;
