c++ - Replace GetInstanceOfClass1()->GetInstanceOfClass2() with extern? -


what happen if "shorten" call:

getinstanceofclass1()->getinstanceofclass2();

(where instance of class2 member of class1) extern function declared in class1.cpp:

extern void getinstanceofclass2() {    getinstanceofclass1()->getinstanceofclass2(); }

will compiler (clang) produce inefficient code? ugly, bad idea actually?
