• Up to Parent: TLightweightSemaphore

Delphi

function WaitFor(Timeout: Cardinal = INFINITE): TWaitResult; overload; override;

C++

Description

Blocks the calling thread until the TLightweightSemaphore is in signaled state or until the specified timeout is over.

However, the blocking does not occur immediately. WaitFor first spends a few CPU cycles in a spin-loop and then blocks the thread if the semaphore is still not in the signaled state.

WaitFor returns a TWaitResult.
