[pdf-devel] about PDF_OBJ_NULL

[Jin Chen-Xin]

Hello Everyone,

I'm Chinese and I live in Shanghai, China. I have written C code for about 4 
years.
I'm not familiar with GNU and PDF.
I've read Hackers Guide and got a copy of source code from bzr.


I've  read the  GNU PDF Library Reference and
I found C statements like "if (integer_obj != PDF_OBJ_NULL) ... " in 
<3.2 PDF Object>.
I think instance of structure could't be compared in this way.
Could I give a patch to fix it?
(see the attacment)
