Thanks for the review. Below a new version.
#include <pty.h>
#include <utmp.h>
#include <unistd.h>
int forkpty(int *m, char *name, const struct termios *tio, const struct winsize *ws)
{
int s, ec, p[2];
pid_t pid;
if (openpty(m, &s, name, tio, ws) < 0) return -1;
if (pipe2(p, O_CLOEXEC)) {
close(s);
goto fail;
}
pid = fork();
if (!pid) {
close(*m);
close(p[0]);
ec = login_tty(s);
while (write(p[1], &ec, sizeof ec) < 0);
if (ec) _exit(127);
close(p[1]);
return 0;
}
close(s);
close(p[1]);
if (pid > 0) read(p[0], &ec, sizeof ec);
close(p[0]);
if (pid > 0) {
if (!ec) return pid;
waitpid(pid, &(int){0}, 0);
}
fail:
close(*m);
return -1;
}
