Hi FPC experts.
I read this thread in the list archive and as I'm very interested in
this topic (since years), I'm very happy do see this evolving and would
like to provide some comment (and maybe contribute some code once I'm up
to speed with FPC) and, of course, ask questions.
1) How is the state on this issue? Does the latest released version of
the FPC RTL already provide a decent implementation of the threading
primitives known from Delphi ? (e.g. TThread.Suspend,
TThread.Synchronize, TEvent, TCriticalSection, TThreadList, etc) as well
for Linux as for Windows etc.? What about WinCE on ARM and Linux on ARM
and 68K ?
2) IMHO FPC is a lot about platform independency. In Delphi/Kylix there
never was a decent platform independent way of inter thread message
passing. Are there any plans on this ? IMHO a perfect way would need a
language enhancement (a way to fire events that are to run in another
thread context, which would also involve enhancing/creating the message
scheduler in the RTL to work not only for the main thread but for any
worker thread, too), but supposedly a thing easier to agree about could
be something like a "TThreadMessage" class in the RTL that fires an
event in the main thread when a message from a worker thread comes in
and for worker threads provides a means to check if a message is
available and optionally wait for one.
3) Does TTimer work in Linux, now, ? Last time I checked I did not get
