SYNOPSIS

9       #include <libexplain/select.h>
10       void explain_select_or_die(int nfds, fd_set *readfds, fd_set *writefds,
11       fd_set *exceptfds, struct timeval *timeout);

DESCRIPTION

14       The explain_select_or_die function is used to call the select(2) system
15       call.   On  failure  an explanation will be printed to stderr, obtained
16       from explain_select(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_select_or_die(nfds, readfds, writefds, exceptfds, timeout);

24
25       readfds The readfds, exactly as to be passed to  the  select(2)  system
26               call.
27
28       writefds
29               The  writefds,  exactly as to be passed to the select(2) system
30               call.
31
32       exceptfds
33               The exceptfds, exactly as to be passed to the select(2)  system
34               call.
35
36       timeout The  timeout,  exactly  as to be passed to the select(2) system
37               call.
38
39       Returns:
40               This function only returns on success.  On failure,  prints  an
41               explanation and exits.
