Hi,
While investigating http://bugs.freepascal.org/view.php?id=14335 I ran into the
following peculiarities. Please, comment and tell for which item you want bug
reports, if any. I tested on i386-linux.
1. The docs of GetThreadId seems to contain a typo:
http://lazarus-ccr.sourceforge.net/docs/rtl/system/getthreadid.html
"GetThreadID returns the current process ID." -> should be thread ID.
2. The docs of MainThreadID say it is unused. But it is used in
TThread.Synchronize.
http://lazarus-ccr.sourceforge.net/docs/rtl/classes/mainthreadid.html
Given the following program:
program project1;
{$mode objfpc}{$H+}
uses
//cthreads,
Classes;
begin
writeln('GetThreadID=', GetThreadID);
writeln('GetCurrentThreadID=', GetCurrentThreadId);
writeln('MainThreadID=', MainThreadID);
end.
3. If cthreads is not used, all values are 1. No problem with that, although I am
not sure those are real thread id, at least on i386-win32 the value changes on each
run, e.g. 1908, 576, maybe because threadmanager is already included in windows.
Anyway, this is not a problem, as long as they all have the same value in a single
threaded application
If cthreads is used, I get the following output:
GetThreadID=3084795456
GetCurrentThreadID=3085236992
MainThreadID=3085236992
4. What is the difference between GetThreadID and GetCurrentThreadID? This code runs
in the same thread, so I expect the same value.
Vincent
