ICLRMemoryNotificationCallback::OnMemoryNotification Method
Notifies the common language runtime (CLR) of the memory load on the computer.
HRESULT OnMemoryNotification (
[in] EMemoryAvailable eMemoryAvailable
);
Parameters
- eMemoryAvailable
[in] One of the EMemoryAvailable values, indicating the memory pressure the computer is currently experiencing.
Return Value
HRESULT |
Description |
|---|---|
S_OK |
OnMemoryNotification 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. After a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE. |
Remarks
The CLR registers a callback to OnMemoryNotification by using a call to the IHostMemoryManager::RegisterMemoryNotificationCallback method. The runtime uses the information returned in the callback to free additional memory when the host reports that memory resources are running low.
