Hello @fxfactorial
From the current example:
auto p = Popen({"grep", "f"}, output{PIPE}, input{PIPE});
const char* msg = "one\ntwo\nthree\nfour\nfive\n";
p.send(msg, strlen(msg));
auto res = p.communicate(nullptr, 0);
std::cout << res.first.buf.data() << std::endl;
res.second.buf
is basically the error data. Does this information help you with your case ?
