.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_SetRecursionDepth\fR with \fIdepth\fR equal to 0.
|
|
|
|
