| 8 | '\" The definitions below are for supplemental macros used in Tcl/Tk |
| 9 | '\" manual entries. |
| 10 | '\" |
| 11 | '\" .AP type name in/out ?indent? |
| 12 | '\" Start paragraph describing an argument to a library procedure. |
| 13 | '\" type is type of argument (int, etc.), in/out is either "in", "out", |
| 14 | '\" or "in/out" to describe whether procedure reads or modifies arg, |
| 15 | '\" and indent is equivalent to second arg of .IP (shouldn't ever be |
| 16 | '\" needed; use .AS below instead) |
| 17 | '\" |
| 18 | '\" .AS ?type? ?name? |
| 19 | '\" Give maximum sizes of arguments for setting tab stops. Type and |
| 20 | '\" name are examples of largest possible arguments that will be passed |
| 21 | '\" to .AP later. If args are omitted, default tab stops are used. |
| 22 | '\" |
| 23 | '\" .BS |
| 24 | '\" Start box enclosure. From here until next .BE, everything will be |
| 25 | '\" enclosed in one large box. |
| 26 | '\" |
| 27 | '\" .BE |
| 28 | '\" End of box enclosure. |
| 29 | '\" |
| 30 | '\" .CS |
| 31 | '\" Begin code excerpt. |
| 32 | '\" |
| 33 | '\" .CE |
| 34 | '\" End code excerpt. |
| 35 | '\" |
| 36 | '\" .VS ?version? ?br? |
| 37 | '\" Begin vertical sidebar, for use in marking newly-changed parts |
| 38 | '\" of man pages. The first argument is ignored and used for recording |
| 39 | '\" the version when the .VS was added, so that the sidebars can be |
| 40 | '\" found and removed when they reach a certain age. If another argument |
| 41 | '\" is present, then a line break is forced before starting the sidebar. |
| 42 | '\" |
| 43 | '\" .VE |
| 44 | '\" End of vertical sidebar. |
| 45 | '\" |
| 46 | '\" .DS |
| 47 | '\" Begin an indented unfilled display. |
| 48 | '\" |
| 49 | '\" .DE |
| 50 | '\" End of indented unfilled display. |
| 51 | '\" |
| 52 | '\" .SO |
| 53 | '\" Start of list of standard options for a Tk widget. The |
| 54 | '\" options follow on successive lines, in four columns separated |
| 55 | '\" by tabs. |
| 56 | '\" |
| 57 | '\" .SE |
| 58 | '\" End of list of standard options for a Tk widget. |
| 59 | '\" |
| 60 | '\" .OP cmdName dbName dbClass |
| 61 | '\" Start of description of a specific option. cmdName gives the |
| 62 | '\" option's name as specified in the class command, dbName gives |
| 63 | '\" the option's name in the option database, and dbClass gives |
| 64 | '\" the option's class in the option database. |
| 65 | '\" |
| 66 | '\" .UL arg1 arg2 |
| 67 | '\" Print arg1 underlined, then print arg2 normally. |

| 266 | information will be written. For \fBTcl_ValidateAllMemory\fR, name of |
| 267 | the file from which the call is being made (normally \fB__FILE__\fR). |

| 273 | .SH DESCRIPTION |
| 274 | These functions provide access to Tcl memory debugging information. |
| 275 | They are only functional when Tcl has been compiled with |
| 276 | \fBTCL_MEM_DEBUG\fR defined at compile-time. When \fBTCL_MEM_DEBUG\fR |
| 277 | is not defined, these functions are all no-ops. |
| 278 | .PP |
| 279 | \fBTcl_DumpActiveMemory\fR will output a list of all currently |
| 280 | allocated memory to the specified file. The information output for |
| 281 | each allocated block of memory is: starting and ending addresses |
| 282 | (excluding guard zone), size, source file where \fBckalloc\fR was |
| 283 | called to allocate the block and line number in that file. It is |
| 284 | especially useful to call \fBTcl_DumpActiveMemory\fR after the Tcl |
| 285 | interpreter has been deleted. |
| 286 | .PP |
| 287 | \fBTcl_InitMemory\fR adds the Tcl \fBmemory\fR command to the |
| 288 | interpreter given by \fIinterp\fR. \fBTcl_InitMemory\fR is called |
| 289 | by \fBTcl_Main\fR. |
| 290 | .PP |
| 291 | \fBTcl_ValidateAllMemory\fR forces a validation of the guard zones of |
| 292 | all currently allocated blocks of memory. Normally validation of a |
| 293 | block occurs when its freed, unless full validation is enabled, in |
| 294 | which case validation of all blocks occurs when \fBckalloc\fR and |
| 295 | \fBckfree\fR are called. This function forces the validation to occur |
| 296 | at any point. |
