int Tcl_SetRecursionLimit(interp,
depth)
- 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.
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.
