I have a TIdTCPClient that sends commands to a TIdCmdTCPServer.
I have an additional thread that reads messages from server. It is protected
with a CriticalSection so as to not interfere with SendCmd's results.
Basically I do...
while not Terminated and Data.Client.IOHandler.Connected do
begin
// Enter critical section
...
// Check if something to read
line := Data.Client.IOHandler.ReadLn(LF, SOME_TIMEOUT);
// Leave critical section
...
end
There are two problems with this implementation:
1) The thread is busy-waiting.
2) SOME_TIMEOUT should be as small as possible to leave the critical section
as soon as possible.
My questions are:
1) Is there anyway to use an INFINITE_TIMEOUT (to avoid busy-waiting) and
"wake-up" the IOHandler from it's readln operation when the section is
needed?
2) If not, what about using a very very small timeout (say 100 ms) and then
sleeping some seconds outside the critical section?
Thanks for your help!
