FSDMGR_ResizeCache (Windows Embedded CE 6.0)

1/6/2010

This function resizes a cache.

It is called by a File System Disk Manager (FSDMGR) for disk cache.

Syntax

DWORD FSDMGR_ResizeCache(
    DWORD dwCacheId,
    DWORD dwSize,
    DWORD dwResizeFlags
);

Parameters

• dwCacheId
  [in] Cache ID value returned by the FSDMGR_CreateCache function.

• dwSize
  [in] New number of blocks for the cache.

• dwResizeFlags
  [in] This parameter can be set to CACHE_FLAG_WARM to preload the cache, starting with location set in the dwStart parameter of FSDMGR_Create, until the cache is filled.

  Otherwise, the entire cache is reset after resizing, and anything cached prior to resizing is erased.

Return Value

ERROR_SUCCESS indicates success. A standard Windows API error code indicates failure.

Remarks

If a request is made to expand a cache when there is not enough memory, the cache retains its original size and is not modified.

The cache is flushed prior to resizing, and all cached entries are lost.
