16
18 Tcl_Interp *interp (in) Interpreter whose recursion limit is
19 to be set. Must be greater than zero.
20 int depth (in) New limit for nested calls to Tcl_Eval
22 for interp.

27 At any given time Tcl enforces a limit on the number of recursive calls
28 that may be active for Tcl_Eval and related procedures such as
29 Tcl_GlobalEval. Any call to Tcl_Eval that exceeds this depth is
30 aborted with an error. By default the recursion limit is 1000.
31 Tcl_SetRecursionLimit may be used to change the maximum allowable nest‐
33 ing depth for an interpreter. The depth argument specifies a new limit
34 for interp, and Tcl_SetRecursionLimit returns the old limit. To read
35 out the old limit without modifying it, invoke Tcl_SetRecursionLimit
36 with depth equal to 0.
37 The Tcl_SetRecursionLimit only sets the size of the Tcl call stack: it
39 cannot by itself prevent stack overflows on the C stack being used by
40 the application. If your machine has a limit on the size of the C
41 stack, you may get stack overflows before reaching the limit set by
42 Tcl_SetRecursionLimit. If this happens, see if there is a mechanism in
43 your system for increasing the maximum size of the C stack.
