Hello, I’d like to pass integer data from main.c to httdp-cgi.c. In order to do so, I use pointers, or should say “try to use”, since something doesn’t work. Do you see the mistake? I bet it’s pretty obvious, although I can’t spot it. Regards [edit: typo]

I don’t know about your use of PT_THREADs, but looking at just the single line of C code: sprintf(txt, “%d”, data_ptr); Needs to be sprintf(txt, “%d”, *data_ptr); //<< Dereference pointer (not a FreeRTOS question)

Yeah, it is as you said. It’s only that the formatting on this site treats STAR as a text formatting (italics) ignoring the fact I used CODE formatting. Duh. Pasted the code as an image, hopefully this would work.

Try putting the code inside pre /pre tags too. The problem is probably related to your use of PTHREADS. I’ve had a look at some examples and they seem to have variables declared outside of PTBEGIN but all C code inside PTBEGIN PTEND blocks. In particular I’m looking at static PTTHREAD( handlescript ( struct httpdstate *s ) ) defined in httpd.c. I don’t know what the macros do though so suggest you look them up to ensure you can put code where you have.

It didn’t work, but in the meantime I managed to come up with a solution that doesn’t require mentioned above code, so I’ve progressed. So far it’s doing the job. Many thanks for taking the interest and trying to help 🙂
