VxWorks实现任务间通信的示例代码及解决方案

本示例演示了在VxWorks实时操作系统中如何通过消息队列实现任务间通信，提供了简洁的代码和详细解释。任务间通信在嵌入式系统中至关重要，可确保各任务协同工作。

#include <vxWorks.h>
#include <msgQLib.h>
#include <taskLib.h>

MSG_Q_ID msgQueue;

void taskReceiver()
{
    while (1)
    {
        char message[50];
        msgQReceive(msgQueue, message, sizeof(message), WAIT_FOREVER);
        printf("接收到消息：%s\n", message);
    }
}

void taskSender()
{
    char messageToSend[] = "Hello from Sender!";
    msgQSend(msgQueue, messageToSend, sizeof(messageToSend), WAIT_FOREVER, MSG_PRI_NORMAL);
}

void main()
{
    msgQueue = msgQCreate(10, 50, MSG_Q_FIFO);
    taskSpawn("receiver", 90, 0, 2000, (FUNCPTR)taskReceiver, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0);
    taskSpawn("sender", 90, 0, 2000, (FUNCPTR)taskSender, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0);
}
