                                                                                       explain_accept4_or_die(3)

       The explain_accept4_or_die 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, 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.

       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);

       explain_accept4_or_die - accept a connection on a socket and report errors

       The 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.

accept4(2)
               accept a connection on a socket

       explain_accept4(3)
               explain accept4(2) errors

       exit(2) terminate the calling process

       flags);
