Hi

I found a little strange problem, when using sscanf:

I am writing a small parser for an 3d .OBJ format. I am using sscanf for
parsing. Most of the results are correct, except one place.

Here is the part of input text file:

f 244/16/244 658/12/658 660/11/660

Here is the code I use for reading that :

Code:

// 1 Vertex -- 2 Vertex -- 3 Vertex
text.sscanf("f ?d/?d/?d ?d/?d/?d ?d/?d/?d",
&triangles[ arpos ].vertexes[0].vid[0] ,
&triangles[ arpos ].vertexes[0].vid[1] ,
&triangles[ arpos ].vertexes[0].vid[2] ,

&triangles[ arpos ].vertexes[1].vid[0] ,
&triangles[ arpos ].vertexes[1].vid[1] ,
&triangles[ arpos ].vertexes[1].vid[2] ,

&triangles[ arpos ].vertexes[2].vid[0] ,
&triangles[ arpos ].vertexes[2].vid[1] ,
&triangles[ arpos ].vertexes[2].vid[2] );

But here is what I get as a result:

I tried to reproduce the problem with a new project, but error dissappeared. I have no idea what is causing the problem.

I have uploaded the 2 projects, one is with and another without error, you can find it here http://adogames.com/programming/problem.zip

P.S. Is there D analog of sscanf ?

P.S.S. Another problem I can't reply or create new post at digitalmars newsgroup page somehow, they are just don't get showed.

I think that your messages are being posted (e.g. digitalmars.D.learn:3827, digitalmars.D.learn:3823) -- they just don't show up right away. There's some kind of delay before web interface posts show up. I've seen it. Just a little patience is required.

It's generally better if a newsgroup readers is used to read those newsgroups, but that's not an option for everyone. For more information, see Wiki4D:NewsDmD.

As far as your actual programming questions go, people have replied to your newsgroup posts, and I think you'll find them more useful than any advice I could provide.

Thats the problem I posted once without the problem, now I just can't reply to them !. Or even make a new post, I tried it about 7 times without any luck. 2-3 days ago.

Still thanks for the link, I am going to try and post the reply using my opera news reader, If I have any luck at all.

Yes Opera helped, my replies, now finally arrive. It seems there are some problems with web interface.
