How to call use defined functions before the main function is running in c

I want to call user defined function in C before the Main() function is running.
i.e. I want to run my own function before the main() fuction is running at start of my program.
1 Solution
Easy to do in C++ (constructor for global variable).
In C, depending on the compiler you use, you can specify a different entry point to the standard "main".

What exactly is it that you want to achieve through your pre-main function?
rcarlan, good question i can't see any particular reason to need to do this...
