NAME

explain_getpeername_or_die - get name of peer socket and report errors  

SYNOPSIS

#include <libexplain/getpeername.h>

void explain_getpeername_or_die(int fildes, struct sockaddr *sock_addr, socklen_t *sock_addr_size);  

DESCRIPTION

The explain_getpeername_or_die function is used to call the getpeername(2) system call. On failure an explanation will be printed to stderr, obtained from explain_getpeername(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:

struct sockadd sock_addr;
socklen_t sock_addr_size = sizeof(sock_addr);
explain_getpeername_or_die(fildes, &sock_addr, &sock_addr_size);
fildes
The fildes, exactly as to be passed to the getpeername(2) system call.
sock_addr
The sock_addr, exactly as to be passed to the getpeername(2) system call.
sock_addr_size
The sock_addr_size, exactly as to be passed to the getpeername(2) system call.
Returns:
This function only returns on success, see getpeername(2) for more information. On failure, prints an explanation and exits.
