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.

readfds

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

writefds

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.

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.
