explain_socketpair_or_die(3) - Linux man page
Name
explain_socketpair_or_die - create pair of connected sockets and report errors
Synopsis
#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);
Description
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.
Example
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);
