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

285 Integer value used to initialize or set an integer object.

287 Long integer value used to initialize or set an integer object.
288 .AP Tcl_WideInt wideValue in
290 Wide integer value (minimum 64-bits wide where supported by the
291 compiler) used to initialize or set a wide integer object.
293 .AP Tcl_Obj *objPtr in/out
294 For \fBTcl_SetIntObj\fR, \fBTcl_SetLongObj\fR, and
296 \fBTcl_SetWideIntObj\fR, this points to the object to be converted to
297 integer type. For \fBTcl_GetIntFromObj\fR, \fBTcl_GetLongFromObj\fR,
298 and \fBTcl_GetWideIntFromObj\fR, this refers to the object from which
299 to get an integer or long integer value; if \fIobjPtr\fR does not
300 already point to an integer object (or a wide integer object in the
301 case of \fBTcl_SetWideIntObj\fR and \fBTcl_GetWideIntFromObj\fR,) an
303 attempt will be made to convert it to one.
304 .AP Tcl_Interp *interp in/out
305 If an error occurs during conversion,
306 an error message is left in the interpreter's result object
307 unless \fIinterp\fR is NULL.
309 Points to place to store the integer value
310 obtained by \fBTcl_GetIntFromObj\fR from \fIobjPtr\fR.
311 .AP long *longPtr out
312 Points to place to store the long integer value
313 obtained by \fBTcl_GetLongFromObj\fR from \fIobjPtr\fR.
314 .AP Tcl_WideInt *widePtr out
316 Points to place to store the wide integer value
317 obtained by \fBTcl_GetWideIntFromObj\fR from \fIobjPtr\fR.
323 These procedures are used to create, modify, and read
324 integer and wide integer Tcl objects from C code.
325 \fBTcl_NewIntObj\fR, \fBTcl_NewLongObj\fR,
326 \fBTcl_SetIntObj\fR, and \fBTcl_SetLongObj\fR
327 create a new object of integer type
328 or modify an existing object to have integer type,
330 and \fBTcl_NewWideIntObj\fR and \fBTcl_SetWideIntObj\fR create a new
331 object of wide integer type or modify an existing object to have wide
334 \fBTcl_NewIntObj\fR and \fBTcl_SetIntObj\fR set the object to have the
335 integer value given by \fIintValue\fR,
336 \fBTcl_NewLongObj\fR and \fBTcl_SetLongObj\fR
337 set the object to have the
338 long integer value given by \fIlongValue\fR,
340 and \fBTcl_NewWideIntObj\fR and \fBTcl_SetWideIntObj\fR set the object
341 to have the wide integer value given by \fIwideValue\fR.
342 \fBTcl_NewIntObj\fR, \fBTcl_NewLongObj\fR and \fBTcl_NewWideIntObj\fR
343 return a pointer to a newly created object with reference count zero.
344 These procedures set the object's type to be integer
345 and assign the integer value to the object's internal representation
346 \fIlongValue\fR or \fIwideValue\fR member (as appropriate).
347 \fBTcl_SetIntObj\fR, \fBTcl_SetLongObj\fR
348 and \fBTcl_SetWideIntObj\fR
350 invalidate any old string representation and,
351 if the object is not already an integer object,
352 free any old internal representation.
354 \fBTcl_GetIntFromObj\fR and \fBTcl_GetLongFromObj\fR
355 attempt to return an integer value from the Tcl object \fIobjPtr\fR,
357 and \fBTcl_GetWideIntFromObj\fR attempts to return a wide integer
358 value from the Tcl object \fIobjPtr\fR.
359 If the object is not already an integer object,
360 or a wide integer object in the case of \fBTcl_GetWideIntFromObj\fR
362 they will attempt to convert it to one.
363 If an error occurs during conversion, they return \fBTCL_ERROR\fR
364 and leave an error message in the interpreter's result object
365 unless \fIinterp\fR is NULL.
366 Also, if the long integer held in the object's internal representation
367 \fIlongValue\fR member can not be represented in a (non-long) integer,
368 \fBTcl_GetIntFromObj\fR returns \fBTCL_ERROR\fR
369 and leaves an error message in the interpreter's result object
370 unless \fIinterp\fR is NULL.
371 Otherwise, all three procedures return \fBTCL_OK\fR and
372 store the integer, long integer value
374 or wide integer in the address given by \fIintPtr\fR, \fIlongPtr\fR
377 respectively. If the object is not already an integer or wide integer
378 object, the conversion will free any old internal representation.
