explain_socket_or_die - create an endpoint and report errors

#include <libexplain/socket.h>

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

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);
The domain, exactly as to be passed to the socket(2) system call.
The type, exactly as to be passed to the socket(2) system call.
The protocol, exactly as to be passed to the socket(2) system call.
This function only returns on success. On failure, prints an explanation and exits.

socket(2)
create an endpoint for communication
explain_socket(3)
explain socket(2) errors
exit(2)
terminate the calling process
