FONTOBJ_pvTrueTypeFontFile function

The FONTOBJ_pvTrueTypeFontFile function retrieves a user-mode pointer to a view of a TrueType, OpenType, or Type1 font file.

Syntax


PVOID FONTOBJ_pvTrueTypeFontFile(
  FONTOBJ *pfo,
  ULONG *pcjFile
);

Parameters

pfo

Pointer to the FONTOBJ structure with which the TrueType, PostScript OpenType, or PostScript Type1 font is associated.

pcjFile

Pointer to a location in which GDI returns the size, in bytes, of the view of the font file.

Return value

FONTOBJ_pvTrueTypeFontFile returns a pointer to a user-mode view of a font file upon success. If the FONTOBJ structure identifies a Type1 font, the return value is a pointer to the memory-mapped image of the pfb file. Otherwise, this function returns NULL.

Remarks

FONTOBJ_pvTrueTypeFontFile should be called only for TrueType, OpenType, or Type1 fonts. The pointer returned by FONTOBJ_pvTrueTypeFontFile is valid only within the scope of the calling DrvTextOut function. That is, the driver should not assume that the pointer returned by this function is valid upon exiting DrvTextOut and returning control to GDI.
