The question is now: Why does this work ?
If BeginThread initializes the stack which needs to be done to make
external threads work it will work with this example
too. Did the creator of this code find a regular solution for this
problem or did he just work around the problem by making
external threads internal ?
I took a quick look at the vortex library.
The "magic" happens in those two functions that are passed in the
initialization section. Those tell the vortex library to not use it's
own threading creation and destruction methods, but to let the calling
application (in this case the FPC one) create the threads. That was a
rather intelligent approach by the developers of the vortex library as
it allows threading systems that need special initialisation (like ours)
to be used.
Effectively those calls start a "FPC internal" thread and is the best
way to circumvent external thread problems.
