好的,我可以帮您写一个程序,使用BOOST的命名管道实现两个进程之间的双向通信。以下是示例代码:
进程1:
```c++
#include <iostream>
#include <boost/interprocess/ipc/message_queue.hpp>
#include <boost/interprocess/ipc/named_mutex.hpp>
#include <boost/interprocess/sync/scoped_lock.hpp>
using namespace boost::interprocess;
int main()
{
// 创建命名管道
message_queue mq(open_or_create, "my_queue", 100, sizeof(int));
named_mutex mtx(open_or_create, "my_mutex");
while (true)
{
// 先锁定互斥量
scoped_lock<named_mutex> lock(mtx);
// 从命名管道中读取数据
int num;
unsigned int priority;
size_t recvd_size;
mq.receive(&num, sizeof(num), recvd_size, priority);
// 处理数据
std::cout << "Received: " << num << std::endl;
// 向命名管道中写入数据
int result = num * 2;
mq.send(&result, sizeof(result), 0);
}
return 0;
}
```
进程2:
```c++
#include <iostream>
#include <boost/interprocess/ipc/message_queue.hpp>
#include <boost/interprocess/ipc/named_mutex.hpp>
#include <boost/interprocess/sync/scoped_lock.hpp>
using namespace boost::interprocess;
int main()
{
// 打开命名管道
message_queue mq(open_only, "my_queue");
named_mutex mtx(open_only, "my_mutex");
while (true)
{
// 先锁定互斥量
scoped_lock<named_mutex> lock(mtx);
// 向命名管道中写入数据
int num = 42;
mq.send(&num, sizeof(num), 0);
// 从命名管道中读取数据
int result;
unsigned int priority;
size_t recvd_size;
mq.receive(&result, sizeof(result), recvd_size, priority);
// 处理数据
std::cout << "Result: " << result << std::endl;
}
return 0;
}
```
这是一个简单的例子,您可以根据自己的需求进行修改。希望能对您有所帮助!
