Functions problem

[itportal]

Hello,

I've got the following problem. FuncB uses recursion and calls itself.
Sometimes FuncB calls FuncA, but then FuncA should call FuncB ... which
actually returns an error..

void FuncA(){
FuncB();
}

void FuncB(){
FuncB();
FuncA();
}

Ani ideas how to make that thing work ...

What error? If your call stacks goes out of limit, probably you should
write something like

void FuncA(){
if ( "not enough yet")
FuncB();
}
void FuncB(){
FuncB();
if ( "not enough yet")
FuncA();
}

somehow the recursion must stop at some time

The recursion has an end, but I get:
"conflicting types for 'FuncB' "

[itportal]

plus:
"previous implicit declaration of 'FuncB' was here"

It's still a bit unclear what the exact error is, is the compiler
complaining about the return type of function FuncB? Could you post the
whole and complete message, and even some code, may-be?

Did you declare FuncB before using it in FuncA? It sounds as though
perhaps you didn't.

If that's not it, then I suggest that you should post the actual code
which causes this problem, because nothing in the snippet you posted is
missing whatever it is that's causing your code not to work.

Could you possibly have mistaken a statement that calls FuncB, and a
statement that defines FuncB

Like:

// defines the function, make the following code aware there is such a
function, but does not call it
void FuncB(int j, int k);
// calls the function
FuncB(j,k);

the difference is the types you declare in a definition, "void" as
return, and two "ints" for the parameters in this example.

The code is very long an complicated.

I have probably made wrong declarations. I declared the functions and
now I get the error:
[Linker error] undefined reference to `FuncA'

[itportal]

Oppps ... I've mistaken the name of the funcs.

Now everything is OK.

The problem had been that I haven't decalred the funcs. So long code
that I get lost in it ;)
