Re: Changing entry point function

[Premk]

We have a set of test modules which are derived from a specific base
class . All the .cpp files have their own main functions.
I'm writing a small module to automate all these classes.
I just want to implement it in a way that affects the existing modules
to the least.

I wanted the new main(from my class) function to be called when the
automation is executed ..
I got away of the different main functions by using the --allow-
multiple-definitions flag of the linker.

I understand the design of the other classes can be changed to achieve
this, but the org wont allow this.
