◆ db_shutdown_driver()

int db_shutdown_driver ( dbDriver driver)

Closedown the driver, and free the driver structure.

Note: the management of the memory for the driver structure probably should be handled differently.

db_start_driver() could take a pointer to driver structure as an argument, instead of returning the pointer to allocated then there would be no hidden free required

driverpointer to dbDriver to be freed
0 on success
-1 on error
