explain_setsockopt_or_die — get and set options on sockets and report errors

Synopsis

#include <libexplain/setsockopt.h>

void explain_setsockopt_or_die(int fildes, int level, int name, void *data, socklen_t data_size);

Description

The explain_setsockopt_or_die function is used to call the setsockopt(2) system call.  On failure an explanation will be printed to stderr, obtained from explain_setsockopt(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_setsockopt_or_die(fildes, level, name, data, data_size);
fildes

The fildes, exactly as to be passed to the setsockopt(2) system call.

level

The level, exactly as to be passed to the setsockopt(2) system call.

name

The name, exactly as to be passed to the setsockopt(2) system call.

data

The data, exactly as to be passed to the setsockopt(2) system call.

data_size

The data_size, exactly as to be passed to the setsockopt(2) system call.

Returns:

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