explain_socketpair_or_die3
Create pair of connected sockets and report errors
Usage
#include <libexplain/socketpair.h>
void explain_socketpair_or_die(int domain, int type, int protocol, int *sv);
int explain_socketpair_on_error(int domain, int type, int protocol, int *sv);
Overview
The explain_socketpair_or_die function is used to call the socketpair(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_socketpair(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_socketpair_on_error function is used to call the socketpair(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_socketpair(3) function, but still returns to the caller.
domain
|
The domain, exactly as to be passed to the socketpair(2) system call. |
|---|---|
type
|
The type, exactly as to be passed to the socketpair(2) system call. |
protocol
|
The protocol, exactly as to be passed to the socketpair(2) system call. |
sv
|
The sv, exactly as to be passed to the socketpair(2) system call. |
Return value
The explain_socketpair_or_die function only returns on success, see socketpair(2) for more information. On failure, prints an explanation and exits, it does not return.
The explain_socketpair_on_error function always returns the value return by the wrapped socketpair(2) system call.
Examples
The explain_socketpair_or_die function is intended to be used in a fashion similar to the following example:
explain_socketpair_or_die(domain, type, protocol, sv);Releases
