Syntax

HRESULT Enter (  
    [in] DWORD option  
);

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

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.

Enter mirrors the Win32 EnterCriticalSection function.

Note

This method does not return until the critical section is entered.
