fork_exec prog args ~stdin ~stdout ~stderr ~setuid ~setgid forks a new process that executes the program in file prog, with arguments args. The pid of the new process is returned immediately; the new process executes concurrently with the current process.

The function raises EPERM if when using set{gid,uid} and the user id is not 0.

The standard input and outputs of the new process are connected to the descriptors stdin, stdout and stderr.

The close_on_exec flag is cleared from stderrstdout and stdin so it's safe to pass in fds with close_on_exec set.
