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.
