It seems that what you want is an inline C function. I don't think
this is part of the C language standard but gcc seems to have its own
method of doing this. Just do a find on 'inline' in the Frameworks to
see how it's done. Look at CGBase.h for instance.

What about using #pragma once at the top of the header file? The
other solution is to move the functions to a C file and move just
the function definitions to header files. I prefer the second for
readability. I usually have a utils.c and a utils.h. I'm not a big
fan of function implementations in header files.

Hi guys, I've few functions that I'm keeping on an external .h file.
If the header is included in more than a class I get duplicate symbol
error. I tried using #ifndef which I use on my C++ classes but didn't
bring any luck. I had a look to the various headers in the framework
and I saw they use the following sintax:
#define VEC_ZERO_2(a) \
{ \
(a)[0] = (a)[1] = 0.0; \
}
Isn't there a way to achieve the same but having parameters and
returns typed?
