DESCRIPTION

15       The  explain_wait3_or_die  function is used to call the wait3(2) system
16       call.  On failure an explanation will be printed  to  stderr,  obtained
17       from  explain_wait3(3),  and  then  the  process  terminates by calling
18       exit(EXIT_FAILURE).

25               call.
26
27       options The options, exactly as to be passed  to  the  wait3(2)  system
28               call.

31               call.
