Returns a pointer to file driver information
Procedure:
H5P_GET_DRIVER_INFO ( plist_id )
Signature:
const void *H5Pget_driver_info(
hid_t plist_id
)
Parameters:
hid_t plist_id IN: File access or data transfer property list identifier
Description:
H5P_GET_DRIVER_INFO returns a pointer to file driver-specific information for the low-level driver associated with the file access or data transfer property list plist_id.
The pointer returned by this function points to an “uncopied” struct. Driver-specific versions of that struct are defined for each low-level driver in the relevant source code file H5FD*.c. For example, the struct used for the MULTI driver is H5FD_multi_fapl_t defined in H5FDmulti.c.
If no driver-specific properties have been registered, H5P_GET_DRIVER_INFO returns NULL.
Returns:
Returns a pointer to a struct containing low-level driver information. Otherwise returns NULL.
NULL is also returned if no driver-specific properties have been registered. No error is pushed on the stack in this case.
Example:
