Re: Startup function before main.

["Uday Karan" <uday.karan@gmail.com>]

I really don't understand what is the need to have a
initialization/start up routine before main().  Main is just like any
other function except that it works as a default entry point to which
the glibc start up code makes a call to.

You can have a function main() as your start up routine that calls
your application's main functions app_main() or something similar. 
You can do all your start up code in main itself and then call
app_main().

Simulating what you are trying to achieve here should not be very
difficult.  You can tweak your environment and stuff in main().
