How to return to main()?

let's say the main() calls for function1, and function1 calls for function 2.
is there a way to return (not necessarily with a value) directly to main?

for example:



is there a command that takes the program back to main?

thanks in advanced!

Perhaps it would be better for main() to call func2() directly.

There are the setjmp() and longjmp() functions, but you should really work on your program structure before resorting to using these functions.

Your example shows func1() returning anyway after calling func2(), so really there is nothing else to do.

Even if func1() did do something (say based on the success/fail of func2()), this is easily achieved (and the best approach) by having func2() return a result, and for func1() to test that result.

Or, trivially, you could have func1 return immediately after calling func2.

Each function call pushes that function's block onto the stack and as each function returns it pops its block off of the stack. Attempting to bypass normal calls and returns means that you also need to clean up the stack on your own. Why wish for such a mess?

thanks guys.

OK, yeah, that makes much more sense.
thanks for the tip.
