hi;
i have a project with many modules. my questions are :
-if functions of module_superior call functions of module_inferior can i access global variable of module_superior in module_inferior(the superior module in an inferior module) by decalaring them as extern?
-if functions of module_superior call functions of module_inferior can i define a global variable in module_inferior then modify it in module_superior then read it in module_inferior?
which solution is the best?
thanks
