Not that I noticed, no.  Did you see a slightly <ahem> overweight person
wearing a grey T-Shirt and jeans.  Actually, that's probably not that
helpful.  I was at the LTSP talk / demonstration, the SuSE talk and
spent a lot of the rest of the time drinking coffee next to the .org
village.

Yeah.. That is what the /* for now */ comment was all about. I was trying to
get it to build an empty linked list of the correct number of elements
first.

Yeah, I had noticed this and fixed it. Tho it does not matter yet because we
never succesfully get to the second element. - When we issue malloc for the
first element we suddenly loose our pointer that strtok was holding. - When
we return the first time we find the rest of our buffer empty. - That is the
main problem.

Yeah... You are right. I was going to build it backward and then invert it
but I wanted it the correct way round. - I did not think about it too much
so did not realise that it is more efficient to build it first then invert

Oh ok. If you post a complete code snippet (ie that compiles & runs)
that exhibits the error, I'll help you debug it.

Re: Strange C errors

Hi,

Thanks for your help.

Sorry for replying to myself...

I switched to using strtok_r because it is thread safe and stores its state
variable somewhere I can see.

So,
for the input
  hello world
  this is a test

 for (tok = strtok_r(buf, "\r\n", &state); tok != NULL;
      tok = strtok_r(NULL, "\r\n", &state)) {
  printf("&&%s&&\n", tok);

Oh Wow... Thanks.
Here is it. :-)

I have also attached the Makefile that I am using.

I invoke ./main and then type
Hello World
This is a test
CTRL+D

at it.

Thanks for your time.
(I can join IRC if that helps and then I will post a summary to the list)
