Error mech.c: 232 type error: pointer expected

[blunt80fi]

Hello!

I'm trying to make matlab s-file from c-code, and when I mex the file, it
gives me this kind of error message:

error mech.c: 233 type error: pointer expected

For example in this line the code looks like this:

if(Niner <= 1)

I'm a rookie with c-code and s-files, and I would like to know how to
correct this.. I know what a pointer is, but I don't know what is
wrong in my case.

Thank you!

could you fill in a little more about the code, maybe a more complete listing? is the error generated by a compiler, or when matlab interprets the s-file? I'm not real familiar with s-code and matlab, but I could help with the C.
