| 9 | '\" The definitions below are for supplemental macros used in Tcl/Tk |

| 11 | '\" |
| 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) |
| 18 | '\" |
| 19 | '\" .AS ?type? ?name? |
| 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. |
| 23 | '\" |
| 24 | '\" .BS |

| 26 | '\" enclosed in one large box. |

| 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. |

| 321 | .SH DESCRIPTION |
| 322 | .PP |
| 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, |
| 329 | .VS 8.4 |
| 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 |
| 332 | integer type. |
| 333 | .VE 8.4 |
| 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, |
| 339 | .VS 8.4 |
| 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 |
| 349 | .VE 8.4 |
| 350 | invalidate any old string representation and, |
| 351 | if the object is not already an integer object, |
| 352 | free any old internal representation. |
| 353 | .PP |
| 354 | \fBTcl_GetIntFromObj\fR and \fBTcl_GetLongFromObj\fR |
| 355 | attempt to return an integer value from the Tcl object \fIobjPtr\fR, |
| 356 | .VS 8.4 |
| 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 |
| 361 | .VE 8.4 |
| 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 |
| 373 | .VS 8.4 |
| 374 | or wide integer in the address given by \fIintPtr\fR, \fIlongPtr\fR |
| 375 | and \fIwidePtr\fR |
| 376 | .VE 8.4 |
| 377 | respectively. If the object is not already an integer or wide integer |
| 378 | object, the conversion will free any old internal representation. |
