explain_getsockopt_or_die — get and set options on sockets and report errors

Synopsis

#include <libexplain/getsockopt.h>

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

Description

The explain_getsockopt_or_die function is used to call the getsockopt(2) system call. On failure an explanation will be printed to stderr, obtained from explain_getsockopt(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_getsockopt_or_die(fildes, level, name, data, data_size);
fildes
The fildes, exactly as to be passed to the getsockopt(2) system call.
level
The level, exactly as to be passed to the getsockopt(2) system call.
name
The name, exactly as to be passed to the getsockopt(2) system call.
data
The data, exactly as to be passed to the getsockopt(2) system call.
data_size
The data_size, exactly as to be passed to the getsockopt(2) system call.
Returns:
This function only returns on success. On failure, prints an explanation and exits.
