GetSystemFileCacheSize function (memoryapi.h)
Retrieves the current size limits for the working set of the system cache.
Syntax
BOOL GetSystemFileCacheSize(
[out] PSIZE_T lpMinimumFileCacheSize,
[out] PSIZE_T lpMaximumFileCacheSize,
[out] PDWORD lpFlags
);
Parameters
[out] lpMinimumFileCacheSize
A pointer to a variable that receives the minimum size of the file cache, in bytes. The virtual memory manager attempts to keep at least this much memory resident in the system file cache, if there is a previous call to the SetSystemFileCacheSize function with the FILE_CACHE_MIN_HARD_ENABLE flag.
[out] lpMaximumFileCacheSize
A pointer to a variable that receives the maximum size of the file cache, in bytes. The virtual memory manager enforces this limit only if there is a previous call to SetSystemFileCacheSize with the FILE_CACHE_MAX_HARD_ENABLE flag.
[out] lpFlags
The flags that indicate which of the file cache limits are enabled.
Return value
If the function succeeds, the return value is a nonzero value.
If the function fails, the return value is 0 (zero). To get extended error information, call GetLastError.
Remarks
To compile an application that uses this function, define _WIN32_WINNT as 0x0502 or later. For more information, see Using the Windows Headers.
The FILE_CACHE constants will be defined in the Windows header files starting with the Windows SDK for Windows Server 2008. If you are using header files from an earlier version of the SDK, add the definitions shown in SetSystemFileCacheSize to your code.
