Is it possible to rename function/variable definitions in a shared library. (under RH 9.0) We are writing some code using some 3rd party libraries but we want to hide this for security reaons.

Thx

It might be possible (although tedious) to hack the symbol table and
relocation table of the shared library.  You can use the 'strip' command
to remove all unnecessary symbols from the file. However, I fail to see
how the names of a shared library's entry points affect the security of
your application.  You are aware of how ineffective "security through
obscurity" is?
