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 B]explain_select_or_die function is used to call the I]select(2) system call. On failure an explanation will be printed to I]stderr, obtained from I]explain_select(3), and then the process terminates by calling CW]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);

I]nfds The nfds, exactly as to be passed to the I]select(2) system call.
I]readfds
  The readfds, exactly as to be passed to the I]select(2) system call.
I]writefds
  The writefds, exactly as to be passed to the I]select(2) system call.
I]exceptfds
  The exceptfds, exactly as to be passed to the I]select(2) system call.
I]timeout
  The timeout, exactly as to be passed to the I]select(2) system call.
Returns: This function only returns on success. On failure, prints an explanation and exits.
