[M3devel] thread suspend/resume?

[Jay K]

(just based on the checkin comment, haven't looked at the code)

 

Interesting.
Should we use these sorts of functions more?

  Direct non-Posix somewhat target-dependent thread suspend/resume?
NetBSD appears to have suspend/resume but maybe not "all".
Solaris has them too, thr_suspend((thread_t)pthread), and thr_continue.

I don't see an "all" function but haven't looked fully.

I see some evidence that Linux has them too but haven't tracked it down.

NT already uses SuspendThread/ResumeThread.

That leaves? Nothing at all?

 Ok I should look into Irix, AIX, HP-UX, OpenVMS, Tru64.

 And this stuff doesn't work yet for OpenBSD, it's using user threads.

 

 

Maybe thread suspend/resume is the "portable enough" interface, implement

it fairly directly with #ifdefs and only use the signals/semaphore on few systems?

 

 

(note that Darwin does have the semaphores that are avoided here,

just slightly different Mach semaphores)
