EngFntCacheLookUp function

The EngFntCacheLookUp function retrieves the address of cached font file data.

Syntax


PVOID EngFntCacheLookUp(
  _In_  ULONG FastCheckSum,
  _Out_ ULONG *pulSize
);

Parameters

FastCheckSum [in]

Specifies the checksum for the font.

pulSize [out]

Pointer to a memory location that receives the size, in bytes, of the data.

Return value

On success, this function returns a pointer to the cached data. Otherwise, it returns NULL.

Remarks

The font engine calls the font driver's DrvLoadFontFile entry point when a font file is first loaded. It is in this call that the font driver receives a value for FastCheckSum, which it subsequently uses when it calls this function.
