[ft-devel] Return type and use of FT_Get_X11_Font_Format

[Richard Michael]

Hello,

I'm new to FreeType and C programming in general, but I'm trying to
contribute to inkscape and fix a problem.

I'm trying to determine the font type of a face, and using
FT_Get_X11_Font_Format as discussed yesterday.

I followed the FreeType tutorial to write a short test program, but am
having trouble with the return type of FT_Get_X11_Font_Format (I
think!).

I've done:

FT_String font_face_name = FT_Get_X11_Font_Format( font_face );
printf("%s",font_face_name);

But my program segfaults.  If I print as an integer with:

printf("%d",font_face_name);

It prints "5".

freetype/ftxf86.h indicates FT_Get_X11_Font_Format returns a "Font
format string".  Is that a special type, perhaps an index into an
enumerated set of possible font formats?  Do I need to do something
special to process it, or is it just a string?

I realize no one has the time to teach me C, I just want to know if a
"font format string" and this function require something special.

Thanks,
Richard
