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);

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.

Returns:

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