What is DEFAULT_CC in function declaration?

Question

I'm relatively new to C, and am curious what this syntax means in a function declaration:

int DEFAULT_CC foo(void)

where DEFAULT_CC is probably defined somewhere else as:

#define DEFAULT_CC      "something"

(I realized the previous example I had up had to do with something completely irrelevant).

Answer 1

More likely calling convention. A calling convention defines exactly how values are passed to and returned from a function. Typical values might be cdecl or stdcall. For a comprehensive explanation of x86 conventions, see Wikipedia.

int "cc" foo(void)

wouldn't compile.

Answer 2

Maybe you're messing up C code with makefile notation, because DEFAULT_CC is the standard makefile variable for setting default C compiler.
