How to call different functions with the same name

[lanser]

Hi Gurus,

I have two libraries, called libA and libB and I will create a driver
placed between them, look like following:
libA
|
driver
|
libB
There is a function reference in libA, named foo, so I should
implement it in driver.
But libB has also a function called foo implemented, and I can't let
libA call the foo in libB directly.
Since I compiled by GCC, I try to weaken the foo in libB and provide a
global foo in driver to be linked with libA.
The question is: to implement foo in driver, I have to call the foo in
libB for its functional, how can I do this???
I tried alias, but it doesn't work. libA always called the foo in libB
instead which in driver.

Any suggestion?

There is nothing in the C language that allows two functions with
external linkage to exist in the same program. gcc might offer
something that can do what you want, but it is a non-standard
extension and not part of the language.

So try asking in one of the gnu.gcc.* groups.
