  35 Scans a single file and adds all fonts found to <parameter>set</parameter>.
  36 If <parameter>force</parameter> is FcTrue, then the file is scanned even if
  37 associated information is found in <parameter>cache</parameter>.  If
  38 <parameter>file</parameter> is a directory, it is added to
  39 <parameter>dirs</parameter>. Whether fonts are found depends on fontconfig
  40 policy as well as the current configuration. Internally, fontconfig will
  41 ignore BDF and PCF fonts which are not in Unicode (or the effectively
  42 equivalent ISO Latin-1) encoding as those are not usable by Unicode-based
  43 applications. The configuration can ignore fonts based on filename or
  44 contents of the font file itself. Returns FcFalse if any of the fonts cannot be
  45 added (due to allocation failure). Otherwise returns FcTrue.

  70 Any subdirectories found are added to <parameter>dirs</parameter>.  Calling
  71 this function does not create any cache files.  Use FcDirCacheRead() if
  72 caching is desired.

  82 This function now does nothing aside from returning FcFalse. It used to creates the
  83 per-directory cache file for <parameter>dir</parameter> and populates it
  84 with the fonts in <parameter>set</parameter> and subdirectories in
  85 <parameter>dirs</parameter>. All of this functionality is now automatically
  86 managed by FcDirCacheLoad and FcDirCacheRead.
