explain_socket_or_die — create an endpoint and report errors

Synopsis

#include <libexplain/socket.h>

void explain_socket_or_die(int domain, int type, int protocol);

Description

The explain_socket_or_die function is used to call the socket(2) system call. On failure an explanation will be printed to stderr, obtained from explain_socket(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_socket_or_die(domain, type, protocol);
domain
The domain, exactly as to be passed to the socket(2) system call.
type
The type, exactly as to be passed to the socket(2) system call.
protocol
The protocol, exactly as to be passed to the socket(2) system call.
Returns:
This function only returns on success. On failure, prints an explanation and exits.
