/* * NOTE: The structure of the routines is identical to that of POSIX * Message_queues to leave the option of having unnamed message * queues at a future date. They are currently not part of the * POSIX standard but unnamed message_queues are. This is also * the reason for the apparently unnecessary tracking of * the process_shared attribute. [In addition to the fact that * it would be trivial to add pshared to the mq_attr structure * and have process private message queues.] * * This code ignores the O_RDONLY/O_WRONLY/O_RDWR flag at open * time. * * $Id: mqueuedeletesupp.c,v 1.2 2001-09-27 11:59:17 chris Exp $ */ #include <stdarg.h> #include <pthread.h> #include <limits.h> #include <errno.h> #include <fcntl.h> #include <mqueue.h> #include <rtems/system.h> #include <rtems/score/watchdog.h> #include <rtems/posix/seterr.h> #include <rtems/posix/mqueue.h> #include <rtems/posix/time.h> /*PAGE * * _POSIX_Message_queue_Delete */ void _POSIX_Message_queue_Delete( POSIX_Message_queue_Control *the_mq ) { if ( !the_mq->linked && !the_mq->open_count ) { _Objects_Close( &_POSIX_Message_queue_Information, &the_mq->Object ); _CORE_message_queue_Close( &the_mq->Message_queue, NULL, /* no MP support */ CORE_MESSAGE_QUEUE_STATUS_WAS_DELETED ); _POSIX_Message_queue_Free( the_mq ); #if 0 && defined(RTEMS_MULTIPROCESSING) if ( the_mq->process_shared == PTHREAD_PROCESS_SHARED ) { _Objects_MP_Close( &_POSIX_Message_queue_Information, the_mq->Object.id ); _POSIX_Message_queue_MP_Send_process_packet( POSIX_MESSAGE_QUEUE_MP_ANNOUNCE_DELETE, the_mq->Object.id, 0, /* Not used */ 0 /* Not used */ ); } #endif } }
