/******************************Public*Routine******************************\
*
* Routine Name:
*
* FONTOBJ_pvTrueTypeFontFile
*
* Routine Description:
*
* This routine returns a kernel mode pointer to the start of a
* font file. Despite the name of the routine, the font need not be
* in the TrueType format.
*
* GDI passes this call onto the font driver to do the detailed work.
* The reason for this is that the file image can have the font file
* image embedded in it in a non trivial way. An example of this would
* be the *.ttc format for Far East Fonts. It is not reasonable to
* expect this routine to be able to parse all file formats so that
* resposibility is left to the font drivers.
*
* Arguments:
*
* pfo - a 32-bit pointer to a FONTOBJ structure associated with a font
* file.
*
* pcjFile - the address of a 32-bit unsigend number that receives the
* size of the view of the font file.
*
* Called by:
*
* Printer Drivers in the context of a call to DrvTextOut
*
* Return Value:
*
* If successful, this routine will return a kernel mode view of
* a TrueType font file. If unsuccessful this routine returns NULL.
