SYNOPSIS

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

DESCRIPTION

15       The  explain_getsockopt_or_die  function  is  used to call the getsock‐
16       opt(2) system call.  On failure  an  explanation  will  be  printed  to
17       stderr,  obtained from explain_getsockopt(3), and then the process ter‐
18       minates by calling exit(EXIT_FAILURE).
19
20       This function is intended to be used in a fashion similar to  the  fol‐
21       lowing example:
22              explain_getsockopt_or_die(fildes, level, name, data, data_size);
23
24       fildes  The fildes, exactly as to be passed to the getsockopt(2) system
25               call.
26
27       level   The level, exactly as to be passed to the getsockopt(2)  system
28               call.
29
30       name    The  name,  exactly as to be passed to the getsockopt(2) system
31               call.
32
33       data    The data, exactly as to be passed to the  getsockopt(2)  system
34               call.
35
36       data_size
37               The  data_size,  exactly  as  to be passed to the getsockopt(2)
38               system call.
39
40       Returns:
41               This function only returns on success.  On failure,  prints  an
42               explanation and exits.
