explain_listen_or_die3
Listen for connections on a socket and report errors
Usage
#include <libexplain/listen.h>
void explain_listen_or_die(int fildes, int backlog);
Overview
The explain_listen_or_die function is used to call the listen(2) system call. On failure an explanation will be printed to stderr, obtained from explain_listen(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_listen_or_die(fildes, backlog);- fildes
-
The fildes, exactly as to be passed to the listen(2) system call.
- backlog
-
The backlog, exactly as to be passed to the listen(2) system call.
- Returns:
-
This function only returns on success. On failure, prints an explanation and exits.
