Hi,

I Implementing linux daemon and I need to use several lNet sockets for
Http and Smtp operations.

Because daemon app not have main loop like gui app I create
EventerThread like this:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i consturtor
TMyEventerThread.Create;beginMyEventer := BestEventerClass.Create; //
for Linux epoll eventer will be createdInherited
Create(false);end; procedure TMyEventerThread.Execute;begin  while not
Terminated do    begin    if not MyEventer.CallAction then     
Sleep(10);    end;end; procedure TMyDaemonClass.SomeProc;var 
Http:TLHttpbegin  Http:=TLHttp.Create; 
Http.Eventer:=MyEventerThread.MyEventer; // assign shared eventer from
eventer thread  // do some workend; 
But I have random AV/SIGSEGV errors in random places of lNet library.

In gui app where I call MyEventer.CallAction from Application.OnIdle
same code works fine. But in thread I have big problems (

How to proper use lNet in daemon/threads ?

Please help !

Sorry, it's my fault ! I forgot to use critical section in some place.
All works fine !
