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.
