Enters the critical section that is represented by the current IHostCrst instance.

Syntax

HRESULT Enter (  
    [in] DWORD option  
);  

Parameters

option
[in] One of the WAIT_OPTION values, indicating what action the host should take if the operation blocks.

Return Value

HRESULT Description
S_OK Enter 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.

Remarks
