Then you should include the header file at the top of each file that contains code that calls the function (at least callbacks.c and main.c in your case). If you failed to include the header file, when the compiler sees the function call, it assumes the function has some default args and return value type. Then, when the functions is defined, if it does not match the default, it says that the function was declared twice.
