IHostMemoryManager::GetMemoryLoad Method

Gets the amount of physical memory that is currently in use, and therefore unavailable, as reported by the host.

HRESULT GetMemoryLoad (
    [out] DWORD*  pMemoryLoad, 
    [out] SIZE_T  *pAvailableBytes
);

pMemoryLoad

[out] A pointer to the approximate percentage of total physical memory that is currently in use.

pAvailableBytes

[out] A pointer to the number of bytes available to the common language runtime (CLR).

HRESULT

Description

S_OK

GetMemoryLoad 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.

GetMemoryLoad wraps the Win32 GlobalMemoryStatus function. The value of pMemoryLoad is the equivalent of the dwMemoryLoad field in the MEMORYSTATUS structure returned from GlobalMemoryStatus.

The runtime uses the return value as a heuristic for the garbage collector. For example, if the host reports that the majority of memory is in use, the garbage collector may elect to collect from multiple generations to increase the amount of memory that can potentially become available.
