I'll assume that you ment ``p_is_null()''.
Right.
If you've a copy of the ISO C and C++ manuals, have a look at what
they have to say about ``NULL'' pointers. It's weird.
Really? Hmm. I know that NULL doesn't work as well in C++ as it does
in C, so I've gotten used to using 0 there.
Though if you're referring to the fact that NULL's underlying bit
representation might not be 0, I'm not sure that's a big deal here.
Anyway, for GDB, ``p == NULL'' is recommended to make it clear that
the pointer is being tested and not the underlying value.
Okay, then that's what I'll do.
Just use:
struct foo
{
int mem;
};
which is what is output by gdb_indent.sh and emacs.
Excellent.
