VxWorks任务间通信的实现方法

本示例代码演示了利用VxWorks操作系统提供的消息队列实现任务间通信的方法。

#include "vxWorks.h"
#include "msgQLib.h"

void task1()
{
    MSG_Q_ID msgQId;
    int msg;
    msgQId = msgQCreate(10, sizeof(int), MSG_Q_FIFO);

    while (1)
    {
        msgQReceive(msgQId, &msg, sizeof(int), WAIT_FOREVER);
        printf("task1 received message: %d", msg);
    }
}

void task2()
{
    MSG_Q_ID msgQId;
    int msg = 10;
    msgQId = msgQCreate(10, sizeof(int), MSG_Q_FIFO);

    while (1)
    {
        msgQSend(msgQId, &msg, sizeof(int), WAIT_FOREVER);
        printf("task2 sent message: %d", msg);
    }
}
