NAME
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.
