What do you want to do with that "feature" if it would exist?

yeah sure, you can have a hundred of main()s.
well it won't compile, of course, but don't let that stop you
seriously, if you're trying to do something fancy, you should look at c++: namespaces, classes, static functions, virtual methods etc.
or maybe you can make do with function pointers in plain C.

if you make a program that allows you to start at any arbitrary address, you can have thousands of mains. If you make a program that starts all main-like functions with a main-like name, you can have as many as you like. If you want to make a usable application, use only this one entry point. It makes life a lot easier.

If it is possible to have more than one main function, could you please explain, how to do so?
Thanks in advance.

Code: Select all
int main(int argc, char **argv) {
if (fork()) {
main1(argc, argv);
} else {
main2(argc, argv);
}
}

There's no practical use for two mains, anyway. You could do it just to be clever, but cleverness doesn't make for a good code.

In C I dare say having two main() functions is 1. waste, 2. food for the compiler to complain a lot about. Which of the two shall it link against crt0.o? Ha?
So, short conclusion: Forget about using 2 main() in a c program.
@andrew_baker:weird humour is your mark, it seems *g*. A look at voodoo girl proves that. but anyway, don't throw hammers at kittens. they are so cute. Nails are better.

I agree, stabbing rusty 9" nails through them is less messy than crushing them with a hammer ;]beyond infinity wrote:Nails are better.
