NAME

       explain_waitpid_or_die - wait for process to change state and report errors

SYNOPSIS

       #include <libexplain/waitpid.h>
       int pid = explain_waitpid_or_die(int pid, int *status, int options);

DESCRIPTION

       The  explain_waitpid_or_die  function  is  used  to  call  the waitpid(2) system call.  On
       failure an explanation will be printed to stderr, obtained  from  explain_waitpid(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_waitpid_or_die(pid, status, options);

       pid     The pid, exactly as to be passed to the waitpid(2) system call.

       status  The status, exactly as to be passed to the waitpid(2) system call.

       options The options, exactly as to be passed to the waitpid(2) system call.

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