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_DIRECT
           H5FD_FAMILY
           H5FD_LOG
           H5FD_MPIO
           H5FD_MULTI
           H5FD_SEC2
           H5FD_STDIO   
           H5FD_WINDOWS (Windows only)
If a user defines and registers custom drivers or if additional drivers are defined in an HDF5 distribution, this list will be longer.

The Windows driver, H5FD_WINDOWS, is available only on Windows systems.

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.
