Help is needed

Hi
I'm trying to print a directories struct tree that will look like this:
A
_a
_b
_B
__c
__d
__C
___e
B
_a
_b

I'm doing a recursion, but how can I know how much space is needed before printing after the recursion?

Tcl_SetRecursionLimit(3)				      Tcl Library Procedures					  Tcl_SetRecursionLimit(3)

__________________________________________________________________________________________________________________________________________________

NAME
Tcl_SetRecursionLimit - set maximum allowable nesting depth in interpreter SYNOPSIS
#include <tcl.h> int Tcl_SetRecursionLimit(interp, depth) ARGUMENTS
Tcl_Interp *interp (in) Interpreter whose recursion limit is to be set. Must be greater than zero. int depth (in) New limit for nested calls to Tcl_Eval for interp. _________________________________________________________________ DESCRIPTION
At any given time Tcl enforces a limit on the number of recursive calls that may be active for Tcl_Eval and related procedures such as Tcl_GlobalEval. Any call to Tcl_Eval that exceeds this depth is aborted with an error. By default the recursion limit is 1000. Tcl_SetRecursionLimit may be used to change the maximum allowable nesting depth for an interpreter. The depth argument specifies a new limit for interp, and Tcl_SetRecursionLimit returns the old limit. To read out the old limit without modifying it, invoke Tcl_SetRecur- sionLimit with depth equal to 0. The Tcl_SetRecursionLimit only sets the size of the Tcl call stack: it cannot by itself prevent stack overflows on the C stack being used by the application. If your machine has a limit on the size of the C stack, you may get stack overflows before reaching the limit set by Tcl_SetRecursionLimit. If this happens, see if there is a mechanism in your system for increasing the maximum size of the C stack. KEYWORDS
nesting depth, recursion Tcl 7.0 Tcl_SetRecursionLimit(3)
