实时linux RTAI 下的如何使用RTFIFO代码

#include <stdio.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/mman.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <signal.h>
#include <rtai_shm.h>
#include "parameters.h"

static int end;

static void endme(int dummy) { end=1; }

int main (void)
{
	struct data_str *data;
	signal(SIGINT, endme);
	data = rtai_malloc (nam2num(SHMNAM),1);
	while (!end) {
		printf(" Counter : %d Sine : %f Cosine : %f \n", data->indx_counter, data->sin_value,     data->cos_value);
	}
	rtai_free (nam2num(SHMNAM), &data);
	return 0;
}
