Check the man pages for exact parameters and error handling, but somethinglike this:
  FcPattern *pat, *match;  FcResult result;  char *file;  int index;
  pat = FcPatternCreate ();  FcPatternAddString (pat, FC_FAMILY, "Times");  FcConfigSubstitute (NULL, pat, FcMatchPattern);  FcDefaultSubstitute (pat);  match = FcFontMatch (NULL, pat, &result);
  FcPatternGetString (match, FC_FILE, 0, (FcChar8 **) &file);  FcPatternGetInteger (match, FC_INDEX, 0, &index);
If you use FreeType, at this point you can do:
  FT_New_Face (ftlib, file, id, &face);
to get your face.  Then you can clean up:
  FcPatternDestroy (match);  FcPatternDestroy (pat);

Going through Pango gets you internationalization.  That is, correct renderingof Arabic, Hebrew, Indic, Thai, etc etc etc.  There are a few projects usingPango with OpenGL.  Search the net.
