DebugUtil.h

#ifndef DEBUG_UTIL_H
#define DEBUG_UTIL_H

#include 

int DebugMessage(const char* message)
{
    const int MAX_CHARS = 1023;
           


        

Answer 1

Make the function inline or declare the function in a header file and define it in a cpp file.

inline int DebugMessage(const char* message)
{
    const int MAX_CHARS = 1023;
    static char s_buffer[MAX_CHARS+1];

    return 0;
}

EDIT:

As a comment by Tomalak Geret'kal suggests, it's better to use my latter suggestions than my former and move the function's declaration to a cpp file.
