IHostCrst::SetSpinCount Method

Sets the spin count for the current IHostCrst instance.

HRESULT SetSpinCount (
    [in] DWORD dwSpinCount
);

dwSpinCount

[in] The new spin count for the current IHostCrst instance.

HRESULT

Description

S_OK

SetSpinCount returned successfully.

HOST_E_CLRNOTAVAILABLE

The common language runtime (CLR) has not been loaded into a process, or the CLR is in a state in which it cannot run managed code or process the call successfully.

HOST_E_TIMEOUT

The call timed out.

HOST_E_NOT_OWNER

The caller does not own the lock.

HOST_E_ABANDONED

An event was canceled while a blocked thread or fiber was waiting on it.

E_FAIL

An unknown catastrophic failure occurred. When a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.

On multi-processor systems, if the critical section represented by the current IHostCrst instance is unavailable, a calling thread spins dwSpinCount times before calling IHostSemaphore::Wait on a semaphore associated with the critical section. If the critical section becomes free during the spin operation, the calling thread avoids the wait operation.

The usage of dwSpinCount is identical to the usage of the parameter of the same name in the Win32 InitializeCriticalSectionAndSpinCount function.
