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.
