ENFILE The program-broad Restrict on the overall variety of open up documents is achieved. ENOBUFS or ENOMEM Insufficient memory is out there. The socket can't be made until finally ample sources are freed. EPROTONOSUPPORT The protocol style or the desired protocol is not supported within just this area.
