SYNOPSIS

#include <libexplain/getpeername.h>

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

DESCRIPTION

The B]explain_getpeername_or_die function is used to call the I]getpeername(2) system call. On failure an explanation will be printed to I]stderr, obtained from I]explain_getpeername(3), and then the process terminates by calling CW]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);

I]fildes The fildes, exactly as to be passed to the I]getpeername(2) system call.
I]sock_addr
  The sock_addr, exactly as to be passed to the I]getpeername(2) system call.
I]sock_addr_size
  The sock_addr_size, exactly as to be passed to the I]getpeername(2) system call.
Returns: This function only returns on success, see I]getpeername(2) for more information. On failure, prints an explanation and exits.
