Semaphores (binary and counting) and message queues areprovided.  Also provided are fifos for communication between Real-TimeLinux tasks and Linux processes.  Timeouts are implemented in all primitives..SH "AUTHOR"Jerry Epplin <JerryEpplin@worldnet.att.net>.SH "SEE ALSO".BR rt_mq_destroy (2),.BR rt_mq_init (2),.BR rt_mq_receive (2),.BR rt_mq_send (2),.BR rt_sem_destroy (2), .BR rt_sem_init (2), .BR rt_sem_post (2), .BR rt_sem_trywait (2), .BR rt_sem_wait (2),.BR rt_task_ipc_delete (2), .BR rt_task_ipc_init (2),.BR rtf_ipc_create (2), .BR rtf_ipc_destroy (2), .BR rtf_receive (2), .BR rtf_send (2)
