-.SH NAME
-Tcl_SetRecursionLimit \- set maximum allowable nesting depth in interpreter
-.SH SYNOPSIS
-.nf
-\fB#include <tcl.h>\fR
-.sp
-int
-\fBTcl_SetRecursionLimit\fR(\fIinterp, depth\fR)
-.SH ARGUMENTS
-.AS Tcl_Interp *interp
-.AP Tcl_Interp *interp in
-Interpreter whose recursion limit is to be set.
-Must be greater than zero.
-.AP int depth in
-New limit for nested calls to \fBTcl_Eval\fR for \fIinterp\fR.
-.BE
-
-.SH DESCRIPTION
-.PP
-At any given time Tcl enforces a limit on the number of recursive
-calls that may be active for \fBTcl_Eval\fR and related procedures
-such as \fBTcl_GlobalEval\fR.
-Any call to \fBTcl_Eval\fR that exceeds this depth is aborted with
-an error.
-By default the recursion limit is 1000.
-.PP
-\fBTcl_SetRecursionLimit\fR may be used to change the maximum
-allowable nesting depth for an interpreter.
-The \fIdepth\fR argument specifies a new limit for \fIinterp\fR,
-and \fBTcl_SetRecursionLimit\fR returns the old limit.
-To read out the old limit without modifying it, invoke
-\fBTcl_SetRecursionLimit\fR with \fIdepth\fR equal to 0.
-.PP
-The \fBTcl_SetRecursionLimit\fR 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 \fBTcl_SetRecursionLimit\fR.
-If this happens, see if there is a mechanism in your system for
-increasing the maximum size of the C stack.
