This function releases the controller associated with the given controller handle. Each call to rsm_release_controller must have a matching rsm_get_controller. When all the controller handles associated with a controller are released, the system resources associated with the controller are freed. Attempting to access a controller handle, or attempting to access import or export segments on a released controller handle, is not legal. The results of such an attempt are undefined.
Return Values: Returns 0 if successful. Returns an error value otherwise.
