Re: [Plib-users] Multithreading in FG

[Stuart M. <stu...@bl...>]

Hi,
   I can't see anything obviously wrong with that code, but here's the
solution I used.
 
I used the set of headers for threading from
 
http://www.codeproject.com/threads/thread_class.asp
 
These work on both linux and windows (and cygwin). I got them working
with no knowledge of threading
straight away and they provide a nice clean interface. They also have
mutex and semaphore classes
which are also very handy for threaded apps.
 
The code is small, easy to see what's going on and well documented. Even
if you don't use it it's
probably worth looking at to see if it helps with your problem.
 
   Good luck,
 
Stuart.

Subject: [Plib-users] Multithreading in FG
 
  Hi,
We are using Flightgear version 0.9.4, in which we are trying to
implement multi-threading. In one thread, processing of next frame will
be done and in the other, rendering of the previous frame. Here,
fgMainLoop() is split into two threads, all the processing before
calling fgRenderFrame() in one thread, i.e. subsystem updates,
input/output updates, tile manager updates,  etc., and fgRenderFrame()
in the other thread.

Is this the correct method of splitting processing and rendering of
frame data?

We are using the below to create a thread:
hThread[1] =
CreateThread(NULL,0,(LPTHREAD_START_ROUTINE)fgRenderFrame1,NULL,0,&dwID[
1]);
      CloseHandle(hThread[1]);

Using the above gives us stack dump error.

Please give us a solution as to how to implement threading.
Eagerly waiting for your reply.

Regards,
Hemalatha
