DESCRIPTION

14       The explain_listen_or_die function is used to call the listen(2) system
15       call.   On  failure  an explanation will be printed to stderr, obtained
16       from explain_listen(3), and then  the  process  terminates  by  calling
17       exit(EXIT_FAILURE).
18
19       This  function  is intended to be used in a fashion similar to the fol‐
20       lowing example:
21              explain_listen_or_die(fildes, backlog);
22
23       fildes  The fildes, exactly as to be passed  to  the  listen(2)  system
24               call.
25
26       backlog The  backlog,  exactly  as to be passed to the listen(2) system
27               call.
28
29       Returns:
30               This function only returns on success.  On failure,  prints  an
31               explanation and exits.
