NAME
FcFileScan - scan a font file
SYNOPSIS
#include <fontconfig/fontconfig.h>
FcBool FcFileScan (FcFontSet *set, FcStrSet *dirs, FcFileCache *cache, FcBlanks *blanks, const FcChar8
*file, FcBool force);
DESCRIPTION
Scans a single file and adds all fonts found to set. If force is FcTrue, then the file is scanned even
if associated information is found in cache. If file is a directory, it is added to dirs. Whether fonts
are found depends on fontconfig policy as well as the current configuration. Internally, fontconfig will
ignore BDF and PCF fonts which are not in Unicode (or the effectively equivalent ISO Latin-1) encoding as
those are not usable by Unicode-based applications. The configuration can ignore fonts based on filename
or contents of the font file itself. Returns FcFalse if any of the fonts cannot be added (due to
allocation failure). Otherwise returns FcTrue.
