NAME
explain_getsockname_or_die - get socket name and report errors
SYNOPSIS
#include <libexplain/getsockname.h>
void explain_getsockname_or_die(int fildes, struct sockaddr *sock_addr,
socklen_t *sock_addr_size);
DESCRIPTION
The explain_getsockname_or_die function is used to call the
getsockname(2) system call. On failure an explanation will be printed
to stderr, obtained from explain_getsockname(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 sockaddr sock_addr;
socklen_t sock_addr_size = sizeof(sock_addr);
explain_getsockname_or_die(fildes, &sock_addr, &sock_addr_size);
fildes The fildes, exactly as to be passed to the getsockname(2)
system call.
sock_addr
The sock_addr, exactly as to be passed to the getsockname(2)
system call.
sock_addr_size
The sock_addr_size, exactly as to be passed to the
getsockname(2) system call.
Returns:
This function only returns on success, see getsockaddr(1) for
more information. On failure, prints an explanation and exits.
