EngFntCacheFault function (winddi.h)
The EngFntCacheFault function reports an error to the font engine if the font driver encountered an error reading from or writing to a font data cache.
Syntax
ENGAPI VOID EngFntCacheFault(
[in] ULONG ulFastCheckSum,
[in] ULONG iFaultMode
);
Parameters
[in] ulFastCheckSum
Specifies the checksum for the font.
[in] iFaultMode
Specifies the type of error that occurred. This parameter can be one of the following values:
| Value | Meaning |
|---|---|
| ENG_FNT_CACHE_READ_FAULT | An error occurred during retrieval. |
| ENG_FNT_CACHE_WRITE_FAULT | An error occurred during storage. |
Return value
None
Remarks
If an error occurs while the font driver was reading from or writing to the font data cache, it should report the error to the font engine by a call to this function.
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 ulFastCheckSum, which it subsequently uses when it calls this function.
