IHostCrst Interface

Serves as the host's representation of a critical section for threading.

interface IHostCrst : IUnknown {
    HRESULT Enter (
        [in]  DWORD option
    );
    HRESULT Leave ();
    HRESULT SetSpinCount (
        [in]  DWORD dwSpinCount
    );
    HRESULT TryEnter (
        [in]  DWORD option,
        [out] BOOL  *pbSucceeded
    );
};

Methods

Method	Description
IHostCrst::Enter Method	Enters the critical section.
IHostCrst::Leave Method	Leaves the critical section.
IHostCrst::SetSpinCount Method	Sets the spin count for the critical section.
IHostCrst::TryEnter Method	Attempts to enter the critical section, and reports success or failure immediately.

Remarks

IHostCrst allows the common language runtime (CLR) to communicate directly with the host's representation of a critical section, rather than using Win32 functions such as EnterCriticalSection or LeaveCriticalSection.
