How can I do a wrapper function which calls another function with exactly same name and parameters as the wrapper function itself in global namespace?
For example I have in A.h foo(int bar); and in A.cpp its implementation, and in B.h foo(int bar); and in B.cpp foo(int bar) { foo(bar) }
I want that the B.cpp's foo(bar) calls A.h's foo(int bar), not recursively itself.
How can I do this? I don't want to rename foo.
Update:
A.h is in global namespace and I cannot change it, so I guess using namespaces is not an option?
Update:
Namespaces solve the problem. I did not know you can call global namespace function with ::foo()
Best Answer
does B inherit/implement A at all?
If so you can use
int B::foo(int bar) { ::foo(bar); }to access the foo in the global namespace
or if it does not inherit.. you can use the namespace on B only
namespace B { int foo(int bar) { ::foo(bar); } };
