For a connectionless socket (for datagram protocols, such as UDP), you get EDESTADDRREQ instead.

(The name stands for “text file busy”.) This is not an Inside a C program, when a function fails, you should handle the errors accordingly, or at least record the errors in a log file. Enxio This library is usually included automatically.

All the error names specified by POSIX.1 must have distinct values, with the exception of EAGAIN and EWOULDBLOCK, which may be the same.

For some system calls and library functions (e.g., getpriority(2)), -1 is a valid return on success.
