    Function syntax to return a pointer...

    Hey all. I'm about halfway through a book called "Teach Yourself C in 21 Days." Great book, but I can't find out how to return a pointer from a function. Can anyone give me the syntax, or an example of the declaration?

    Would be most appreciated.

    Returning something is nothing special. But maybe you're looking for something else?
    Code:
    char* foo()
    {
        return malloc(5);
    }
    
    int main()
    {
        char* p = foo();
        free(p);
    }

    Outside of your DOS world, your header file is meaningless.
