EngFntCacheLookUp function (winddi.h)

  • Article

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

Syntax

ENGAPI PVOID EngFntCacheLookUp(
  [in]  ULONG FastCheckSum,
  [out] ULONG *pulSize
);

Parameters

[in] FastCheckSum

Specifies the checksum for the font.

[out] pulSize

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.
