阻止通过 ifstream 对象从 FIFO 读取

#include<iostream>
#include <fstream>
#include<string>

int main() {
    std::ifstream fifo("/path/to/fifo", std::ios::in);
    if (!fifo.is_open()) {
        std::cerr << "Failed to open FIFO."<< std::endl;
        return 1;
    }

    std::string data;
    while (fifo >> data) {
        std::cout << "Received data: "<< data<< std::endl;
    }

    fifo.close();
    return 0;
}

fifo.set(std::ios::in | std::ios::binary);
fifo.set(std::ios::in | std::ios::binary | std::ios::timeout);
