使用Boost C++使用管道将子进程的输出发送到父进程(将标准输出重定向到管道)

#include <boost/process.hpp>
#include <boost/iostreams/device/file_descriptor.hpp>
#include <boost/iostreams/stream.hpp>

boost::process::pipe pipe;

boost::process::child child("your_command", boost::process::std_out > pipe);

boost::iostreams::stream<boost::iostreams::file_descriptor_source> stream(pipe.source);

std::string output;
std::getline(stream, output);

#include <boost/process.hpp>
#include <boost/iostreams/device/file_descriptor.hpp>
#include <boost/iostreams/stream.hpp>
#include <iostream>

int main() {
    boost::process::pipe pipe;
    boost::process::child child("your_command", boost::process::std_out > pipe);
    boost::iostreams::stream<boost::iostreams::file_descriptor_source> stream(pipe.source);

    std::string output;
    std::getline(stream, output);

    std::cout << "子进程的输出：" << output << std::endl;

    return 0;
}
