Hello,
So this is my latest code:
void inline __fastcall lockCriticalSection(TCriticalSection *criticalSection)
{
for(int i = 0; i < 5000; ++i)
{
if(criticalSection->TryEnter())
return;
::Sleep(1);
}
throw Exception("BUG FOUND, CHECK CALL STACK!");
//criticalSection->Acquire();
};
Is it OK?
Regards,
SZ
