       Tcl_SetRecursionLimit - set maximum allowable nesting depth in

       #include <tcl.h>

       Tcl_SetRecursionLimit(interp, depth)

       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.

       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_SetRecursionDepth 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.
