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.
