What about kill() in 11.9 ?

Mantis 1451

filed with proposal to make it clear that wait fork only waits for
immediate subprocesses.

Subject: [sv-ec] Difference between subprocess in wait fork and disable
fork

 

In sections 11.8.1 and 11.8.2, there seems to be a difference in the
definition of a subprocess.  The wait fork sections seems to define a
subprocess as being only those child processes created by the calling
process, whereas the disable fork explicitly includes all of the child's
descendants.

 

The wait fork statement is used to ensure that all child processes
(processes created by the calling process)

have completed their execution. Specifying wait fork causes the calling
process to block until all its subprocesses have completed.

 

and

 

The disable fork statement terminates all active descendants
(subprocesses) of the calling process.

 

One could argue that a child of a child is also created by the calling
process. But the real question is: is this difference intentional? I
don't see why the semantics of a subprocess should be different for
these two constructs.
