DESCRIPTION

14       The explain_waitpid_or_die function is used to call the waitpid(2) sys‐
15       tem  call.   On  failure  an  explanation  will  be  printed to stderr,
16       obtained from explain_waitpid(3), and then the  process  terminates  by
17       calling exit(EXIT_FAILURE).
18
19       This  function  is intended to be used in a fashion similar to the fol‐
20       lowing example:
21              explain_waitpid_or_die(pid, status, options);
22
23       pid     The pid, exactly as to be passed to the waitpid(2) system call.
24
25       status  The status, exactly as to be passed to  the  waitpid(2)  system
26               call.
27
28       options The  options,  exactly as to be passed to the waitpid(2) system
29               call.
30
31       Returns:
32               This function only returns on success.  On failure,  prints  an
33               explanation and exits.
