null pointer complexities

by davidh In reply to Detecting null pointer bu ...

good article. However the language issues surrounding null pointers in C have additional complexities that programmers should understand.

I recommend that all embedded C programmers take a look at the null pointer FAQ at http://www.eskimo.com/~scs/C-faq/s5.html.

Simple Null pointer

by Arvind Bharti In reply to Detecting null pointer bu ...

No doubt article is good. I think null pointer problem can arise only by two ways: malloc or a pointer that can de altered by other application also. That's why such a complex solution is not required, simple null checking will be enough, simple solution for complex null pointer.
