10 '\" The definitions below are for supplemental macros used in Tcl/Tk
13 '\" .AP type name in/out ?indent?
14 '\" Start paragraph describing an argument to a library procedure.
15 '\" type is type of argument (int, etc.), in/out is either "in", "out",
16 '\" or "in/out" to describe whether procedure reads or modifies arg,
17 '\" and indent is equivalent to second arg of .IP (shouldn't ever be
18 '\" needed; use .AS below instead)
21 '\" Give maximum sizes of arguments for setting tab stops. Type and
22 '\" name are examples of largest possible arguments that will be passed
23 '\" to .AP later. If args are omitted, default tab stops are used.
26 '\" Start box enclosure. From here until next .BE, everything will be
27 '\" enclosed in one large box.
30 '\" End of box enclosure.
33 '\" Begin code excerpt.
38 '\" .VS ?version? ?br?
39 '\" Begin vertical sidebar, for use in marking newly-changed parts
40 '\" of man pages. The first argument is ignored and used for recording
41 '\" the version when the .VS was added, so that the sidebars can be
42 '\" found and removed when they reach a certain age. If another argument
43 '\" is present, then a line break is forced before starting the sidebar.
46 '\" End of vertical sidebar.
49 '\" Begin an indented unfilled display.
52 '\" End of indented unfilled display.
55 '\" Start of list of standard options for a Tk widget. The
56 '\" options follow on successive lines, in four columns separated
60 '\" End of list of standard options for a Tk widget.
62 '\" .OP cmdName dbName dbClass
63 '\" Start of description of a specific option. cmdName gives the
64 '\" option's name as specified in the class command, dbName gives
65 '\" the option's name in the option database, and dbClass gives
66 '\" the option's class in the option database.
69 '\" Print arg1 underlined, then print arg2 normally.

262 New limit for nested calls to \fBTcl_Eval\fR for \fIinterp\fR.
267 At any given time Tcl enforces a limit on the number of recursive
268 calls that may be active for \fBTcl_Eval\fR and related procedures
269 such as \fBTcl_GlobalEval\fR.
270 Any call to \fBTcl_Eval\fR that exceeds this depth is aborted with
272 By default the recursion limit is 1000.
274 \fBTcl_SetRecursionLimit\fR may be used to change the maximum
275 allowable nesting depth for an interpreter.
276 The \fIdepth\fR argument specifies a new limit for \fIinterp\fR,
277 and \fBTcl_SetRecursionLimit\fR returns the old limit.
278 To read out the old limit without modifying it, invoke
279 \fBTcl_SetRecursionLimit\fR with \fIdepth\fR equal to 0.
281 The \fBTcl_SetRecursionLimit\fR only sets the size of the Tcl
282 call stack: it cannot by itself prevent stack overflows on the
283 C stack being used by the application. If your machine has a
284 limit on the size of the C stack, you may get stack overflows
285 before reaching the limit set by \fBTcl_SetRecursionLimit\fR.
286 If this happens, see if there is a mechanism in your system for
287 increasing the maximum size of the C stack.
