Notifies the common language runtime (CLR) that the task that the current ICLRTask instance represents is now in an operable state.
HRESULT SwitchIn ( [in] HANDLE threadHandle );
[in] A handle to the physical thread on which the task represented by the current
ICLRTask instance is executing.
|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.|
threadHandle parameter represents a handle to the operating system thread on which the task represented by the current
ICLRTask instance has been scheduled. If impersonation has occurred on this thread, you must call IHostSecurityManager::RevertToSelf before switching in the task.
A call to
SwitchIn without an earlier call to
SwitchOut fails with an HRESULT value of HOST_E_INVALIDOPERATION.
