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_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_SetRecursion-Limit. Tcl_SetRecursionLimit.
       Limit.   If  this happens, see if there is a mechanism in your system for increasing the maximum size
       of the C stack.
