Re: [ft-devel] Return type and use of FT_Get_X11_Font_Format

[David Turner]

Hello Richard,

the problem is that FT_String is defined as "char", not "char*",
so you should really declare your variable as:

FT_String*  font_face_name = FT_Get_X11_Font_Format( font_face );

Yes, I know this is so stooooopid, but we can't change this for
historical reasons. Better use char* instead of FT_String in user
code.
