On failure an explanation will be printed to stderr, obtained from the explain_accept4(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_accept4_on_error function is used to call the accept4(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_accept4(3) function, but still returns to the caller. fildes The fildes, exactly as to be passed to the accept4(2) system call. sock_addr The sock_addr, exactly as to be passed to the accept4(2) system call. sock_addr_size The sock_addr_size, exactly as to be passed to the accept4(2) system call. flags The flags, exactly as to be passed to the accept4(2) system call.RETURN VALUEThe explain_accept4_or_die function only returns on success, see accept4(2) for more information. On failure, prints an explanation and exits, it does not return. The explain_accept4_on_error function always returns the value return by the wrapped accept4(2) system call.EXAMPLEThe explain_accept4_or_die function is intended to be used in a fashion similar to the following example: int result = explain_accept4_or_die(fildes, sock_addr, sock_addr_size, flags);SEE ALSOaccept4(2) accept a connection on a socket explain_accept4(3) explain accept4(2) errors exit(2) terminate the calling processCOPYRIGHTlibexplain version 0.52 Copyright (C) 2009 Peter Miller explain_accept4_or_die(3)
