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

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

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