NAME

       explain_getsockopt_or_die - get and set options on sockets and report errors

SYNOPSIS

       #include <libexplain/getsockopt.h>
       void  explain_getsockopt_or_die(int  fildes,  int  level,  int name, void *data, socklen_t
       *data_size);

DESCRIPTION

       The explain_getsockopt_or_die function is used to call the getsockopt(2) system call.   On
       failure an explanation will be printed to stderr, obtained from explain_getsockopt(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:
              explain_getsockopt_or_die(fildes, level, name, data, data_size);

       fildes  The fildes, exactly as to be passed to the getsockopt(2) system call.

       level   The level, exactly as to be passed to the getsockopt(2) system call.

       name    The name, exactly as to be passed to the getsockopt(2) system call.

       data    The data, exactly as to be passed to the getsockopt(2) system call.

       data_size
               The data_size, exactly as to be passed to the getsockopt(2) system call.

       Returns:
               This function only returns on success.  On  failure,  prints  an  explanation  and
               exits.
