Basically, my goal is to receive continuously values from a TCP/IP connected
device, and at the same time I want to embed all that synchronization stuff
in a DLL.
OnWorkEnd (Indy) event in my DLL fires as required when some DLL functions
are called from an external code (via a callback procedure), but I expected
that in following sequence MyHTTP.Get would produce an infinite loop, which
is not true:
procedure MyHTTP.MyOnWorkEnd(Sender: TObject; AWorkMode: TWorkMode);
begin
if AWorkMode = wmRead then
begin
MyCallbackFunc(pchar(Respnse));
Respnse := pchar(MyHTTP.Get(AURL));
end;
end;
The question is more general and not only Indy specific.
Any suggestions or comments are much appreciated.
