EngFntCacheLookUp function (winddi.h)
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.
