TOPIC:

function LockedCompareExchange(var Target: UInt64; Exch, Comp: UInt64): UInt64; register; overload; inline;
begin
  Result := AtomicCmpExchange(Target, Exch, Comp);
end;  
I can not compile LockedCompareExchange function  because of     AtomicCmpExchange              
Is this function supposed to be added in next version of CT ?                                                                               

Current CT version 7.90, support ALL Interlocked*** functions.

You can find ALL Interlocked*** functions to
C:\codetyphon\fpcsrc\packages\winunits-jedi\src\JwaWinBase.pas

Just add JwaWinBase unit to your "Uses" to use 
LockedCompareExchange function or
LockedCompareExchange64 function


AtomicCmpExchange  do NOT exist to our programming world ....

Thanks you for your answer.

I have added   JwaWinBase.pas
to uses list :
uses
  Classes, SysUtils, Forms, Controls, Graphics, Dialogs,
   JwaWinBase.pas;                                          

Compiler "does not see" JwaWinBase.pas.
I am to add full path "\fpcsrc\packages.....\src " somewhere in configuration?
