This method invokes the resource manager to free memory.

Syntax 

HRESULT ResourceManagerDiscardBytes(
  DWORD 
Bytes
);

Parameters

Bytes

[in] The number of target bytes to discard. If zero, then the resource manager should discard all bytes.

Return Value

If the method succeeds, the return value is D3DM_OK (see D3DM Values).

If the method fails, the return value can be D3DMERR_INVALIDCALL (see D3DMERR Values).

Remarks

The resource manager frees up memory allocations until the number of target bytes is reached. The resource manager follows a least-recently-used (LRU) priority technique.

Note that the number of bytes freed are not guaranteed to be contiguous. Therefore you might not be able to create a resource that takes the number of bytes specified in Bytesafter calling this method.

Requirements

Header d3dm.h
Library D3dm.lib, D3dmguid.lib
Windows Embedded CE Windows CE 5.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
