explain_accept4_or_die(3) Library Functions Manual explain_accept4_or_die(3) NAME explain_accept4_or_die - accept a connection on a socket and report er- rors SYNOPSIS #include <libexplain/accept4.h> int explain_accept4_or_die(int fildes, struct sockaddr *sock_addr, socklen_t *sock_addr_size, int flags); int explain_accept4_on_error(int fildes, struct sockaddr *sock_addr, socklen_t *sock_addr_size, int flags); DESCRIPTION The explain_accept4_or_die function is used to call the accept4(2) sys- tem call. 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, ob- tained 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 VALUE The explain_accept4_or_die function only returns on success, see ac- cept4(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. EXAMPLE The 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 ALSO accept4(2) accept a connection on a socket explain_accept4(3) explain accept4(2) errors exit(2) terminate the calling process COPYRIGHT libexplain version 1.3 Copyright (C) 2009 Peter Miller explain_accept4_or_die(3)
