How to measure a thread stack usage?

I don't know how many threads you are creating but if this were a persistent issue Windows would provide an api.
Do you have any reason to think that your threads are running out of stack?

There is a solution here: http://stackoverflow.com/questions/1740888/determining-stack-space-with-visual-studio/1747499#1747499[^]using http://en.wikipedia.org/wiki/Win32_Thread_Information_Block[^]

but u need to code language

A very simple method of measuring your current stack level is to take the address of a variable that is allocated on the stack, for example:

char* GetCurrentStackLevel()
{
    char a;
    return &a;
}

Then call this function before and inside the function of which you want to measure the stack usage and subtract the two pointers. The stack usage of GetCurrentStackLevel itself will cancel out in that subtraction.

Note that you may not use the returned value for anything else! By the time GetCurrentStackLevel returns, the returned pointer will point to no man's land. It just can be used to measure your current stack level.

{$IFDEF MSWINDOWS}
function currentStackUsage: NativeUInt;
//NB: Win32 uses FS, Win64 uses GS as base for Thread Information Block.
asm
  {$IFDEF WIN32}
  mov eax, fs:[4]  // TIB: base of the stack
  sub eax, esp     // compute difference in EAX (=Result)
  {$ENDIF}
  {$IFDEF WIN64}
  mov rax, gs:[8]  // TIB: base of the stack
  sub rax, rsp     // compute difference in RAX (=Result)
  {$ENDIF}
{$ENDIF}
end;
