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.
