Hi, I am new to FontConfig. I have a FT_Face and I want to get the filename and font index from it. I found FcFreeTypeQueryFace() should be useful. However, what should I put in the second and third argument? I don't quite understand what is mean by "used solely as data for pattern elements" as mentioned in the man page. I tried to put NULL and zero but the call fails. If I put something non-zero, the call success: // something non-null FcChar8 abc[1] ; FcBlanks *b = FcBlanksCreate() ; FcPattern *p = FcFreeTypeQueryFace( face, abc, 0, b ) ; FcChar8 *filename2 ; FcResult result ; FcPattern *matched = FcFontMatch( 0, p, &result); if (FcPatternGetString (matched, FC_FILE, 0, &filename2) != FcResultMatch) std::cout << "oops" << std::endl ; int id ; if (FcPatternGetInteger (matched, FC_INDEX, 0, &id) != FcResultMatch) std::cout << "oops2" << std::endl ; std::cout << "file is " << filename2 << " " << id << std::endl ; It actually works. I want to ask if it is OK to put some dummy non-null pointer to the function? Thanks in advance.
