NAME
       explain_wait3_or_die - wait for process to change state and report errors

SYNOPSIS
       #include <libexplain/wait3.h>
       void explain_wait3_or_die(int *status, int options, struct rusage *rusage);

DESCRIPTION
       The  explain_wait3_or_die function is used to call the wait3(2) system call.  On failure an explanation will be printed to stderr, obtained
       from explain_wait3(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:
	      int pid = explain_wait3_or_die(status, options, rusage);

       status  The status, exactly as to be passed to the wait3(2) system call.

       options The options, exactly as to be passed to the wait3(2) system call.

       rusage  The rusage, exactly as to be passed to the wait3(2) system call.

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