Question

I am wondering if macro definitions can contain space. Let’s take for example this code:

#define MACRO_PARAM int param2

int function(int param1, MACRO_PARAM)
{
    return param1+param2;
}

This works ok with Visual Studio 8 and gcc 3.4.5 (mingw). For me this is good enough for the moment but is this standard? or can I rely on this behavior across different compilers?

Thanks,

Iulian

PS: To answer to the question why would you wanna do that?: I’m using bison flex for a project and I’m trying to make something reentrant (I need to declare some macros for function parameters).

Answer 1

You’ll need to end each line of the definition with a \ (except the last).
