Name: H5Pget_driver
Signature:
hid_t H5Pget_driver( hid_t plist_id )
Purpose:
Returns low-lever driver identifier.
Description:
H5Pget_driver returns the identifier of the low-level file driver associated with the file access property list or data transfer property list plist_id.

Valid driver identifiers with the standard HDF5 library distribution include the following: 

           H5FD_CORE
           H5FD_FAMILY
           H5FD_LOG
           H5FD_MPIO
           H5FD_MULTI
           H5FD_SEC2
           H5FD_STDIO
If a user defines and registers custom drivers or if additional drivers are defined in an HDF5 distribution, this list will be longer.

The returned driver identifier is only valid as long as the file driver remains registered.

Parameters:
Returns:
Returns a valid low-level driver identifier if successful. Otherwise returns a negative value.
