NAME

rt_ipc - IPC Primitives for Real-Time Linux

SYNOPSIS

#define MODULE

#include <linux/kernel.h>
#include <linux/version.h>
#include <linux/errno.h>
#include rt_ipc.h

int rt_task_ipc_init(RT_TASK_IPC * task, void (*fn)(int data), int data, int stack_size, int priority);

int rt_task_ipc_delete(RT_TASK_IPC * task);

int rt_sem_init(rt_sem_t *sem, RT_SEMTYPE type, int init_val);

int rt_sem_destroy(rt_sem_t *sem);

int rt_sem_post(rt_sem_t *sem);

int rt_sem_wait(rt_sem_t *sem);

int rt_sem_trywait(rt_sem_t *sem);

int rt_mq_init(rt_mq_t *mq, int max_msgs, int msg_size);

int rt_mq_destroy(rt_mq_t *mq);

int rt_mq_send(rt_mq_t *mq, char *msg, RT_MQ_PRIO prio, RTIME wait);

int rt_mq_receive(rt_mq_t *mq, char *msg, RTIME wait);

int rtf_ipc_create(unsigned int fifo, int size, int rtl_to_linux);

int rtf_ipc_destroy(unsigned int fifo);

int rtf_receive(unsigned int fifo, void *buf, int count, RTIME timeout);

int rtf_send(unsigned int fifo, void *buf, int count, RTIME timeout);

DESCRIPTION

rt_ipc provides facilities for communication and synchronization among Real-Time Linux tasks. Semaphores (binary and counting) and message queues are provided. Also provided are fifos for communication between Real-Time Linux tasks and Linux processes. Timeouts are implemented in all primitives.
