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_SetRecursionLimit.  If this happens, see if there is a mechanism in your system
       for increasing the maximum size of the C stack.
