NAME
       explain_select_or_die - blah blah and report errors

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

DESCRIPTION
       The  explain_select_or_die  function  is  used  to  call  the  select(2) system call.  On failure an explanation will be printed to stderr,
       obtained from explain_select(3), and then the process terminates by calling exit(EXIT_FAILURE).

       This function is intended to be used in a fashion similar to the following example:
	      explain_select_or_die(nfds, readfds, writefds, exceptfds, timeout);

       nfds    The nfds, exactly as to be passed to the select(2) system call.

       exceptfds

       timeout The timeout, exactly as to be passed to the select(2) system call.

       Returns:
	       This function only returns on success.  On failure, prints an explanation and exits.
