Tcl_SetRecursionLimit(3tcl)

______________________________________________________________________________

NAME

       Tcl_SetRecursionLimit  -  set maximum allowable nesting depth in inter-
       preter

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 nest-
       ing 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_SetRecursionLimit
       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.
