Spawn A Child Process in C++, in Async or Sync manner

All My Sons

child process library written in C++, tested in Windows 10 & Linux environments

use cmake to integrate into your project

add_subdirectory(spawnchild)
add_executable(spawned spawned.cpp)
target_link_libraries(spawned ${SpawnChild_LIBS})

Sync use example:

#include <SpawnChild.h>

std::string input = "";
std::vector<std::string> args = {"-la"};
std::string processPath = "ls";

spawnchild::SyncSpawn lsSpawned(processPath, args, input);

std::string result = lsSpawned.getResult();

Async event driven use example:

#include <mutex>
#include <SpawnChild.h>

std::vector<std::string> args;
std::string processPath = "./child";
spawnchild::AsyncSpawnEvents events;

bool finished = false;
bool isExited = false;

events.onExit = [&isExited, &finished](int code, bool crashed){
    std::mutex mtx;
    mtx.lock();
    if (!crashed){
        isExited = true;
    }
    finished = true;
    mtx.unlock();
};

events.onMessage = [](std::string data){
    std::string got = data;
};
spawnchild::AsyncSpawn childProg(processPath, args, events);

childProg.send("12");

childProg.send("0");

while (!finished);

// child is exited
