 Posted: Mon Nov 20, 2006 1:16 am Post subject: Freeing a thread that WaitsForSingle(Multiple)Object(s) |
 |
|
How to properly terminate and free a thread that waits for windows'
"callback", like when using WaitForSingleObject or
WaitForMultipleObjects?
Example:
While not Terminated do
AHandle := FindFirstChangeNotification(...)
WaitForSingleObject(AHandle, INFINITE)
...
FindCloseChangeNotification(AHandle)
end;
In this example, if the notification doesn't happen, the thread will
wait INFINITE, therefore I can't free it properly from an external
code. Wait functions, because of their blocking nature, (mostly) make
sense if used in a thread, so there must be a "common practise"
approach to this.
And probably a lame question, but is it safe to use Self.Free at the
end of Execute method? I've currently solved the issue by using a
custom message which the thread sends at the end of it's Execute
method, but I'm guessing that there's a "common practise" approach to
this, too. |

Ok, I've solved this by using TThread.FreeOnTerminate, but I still
haven't solved the first issue |
