Hello.
You may use RTLEvents to pause a thread. =>
Program Project1;
{$mode objfpc}{$H+}
uses
{$IFDEF UNIX}
cthreads,
{$ENDIF}
Classes;
Type
{ THelloThread }
THelloThread = class(TThread)
fSleepTime,fThreadNum:integer;
fEvent:PRTLEvent;
procedure Execute; override;
constructor Create(sleepTime,threadNum:integer);
destructor Destroy; override;
end;
var
ThreadArray:array[1..10] of THelloThread;
{ THelloThread }
procedure THelloThread.Execute;
begin
while true do
begin
writeln('Thread ',fThreadNum,' sleeping for ',fsleepTime,' ms');
RTLeventWaitFor(fEvent,fSleepTime);
if Terminated then break;
//don't forget to reset,
RTLeventResetEvent(fEvent);
writeln('Hello From Thread ',fThreadNum);
end;
writeln('Bye from ',fThreadNum);
end;
constructor THelloThread.Create(sleepTime,threadNum: integer);
begin
inherited Create(true);
FreeOnTerminate := true;
fEvent := RTLEventCreate;
fSleepTime := sleepTime;
fThreadNum := threadNum;
Start;
end;
destructor THelloThread.Destroy;
begin
RTLeventdestroy(fEvent);
inherited Destroy;
end;
procedure CreateThreads;
var
l:integer;
begin
for l := low(ThreadArray) to high(ThreadArray) do
ThreadArray[l] := THelloThread.Create(l*1000,l);
end;
procedure StopThreads;
var
l:integer;
begin
for l := low(ThreadArray) to high(ThreadArray) do
begin
ThreadArray[l].Terminate;
RTLeventSetEvent(ThreadArray[l].fEvent); //wake event up for early
terminattion
ThreadArray[l].WaitFor;
end;
end;
begin
CreateThreads;
writeln('Press Any Key To Stop.');
readln;
StopThreads;
writeln('All threads stopped');
readln;
end.

Many thanks ;-)
