IHostTaskManager::ReverseLeaveRuntime Method
Notifies the host that control is leaving the common language runtime (CLR) and entering an unmanaged function that was, in turn, called from managed code.
HRESULT ReverseLeaveRuntime ();
Return Value
HRESULT |
Description |
---|---|
S_OK |
ReverseLeaveRuntime returned successfully. |
HOST_E_CLRNOTAVAILABLE |
The 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. |
E_OUTOFMEMORY |
Not enough memory is available to complete the requested resource allocation. |
Remarks
The CLR calls ReverseLeaveRuntime to inform the host that the currently executing task is returning control to an unmanaged function that was, in turn, called from managed code through platform invoke. Each call to ReverseLeaveRuntime matches a corresponding call to ReverseEnterRuntime.
