 '\" The definitions below are for supplemental macros used in Tcl/Tk
 '\" manual entries.
 '\"
 '\" .AP type name in/out ?indent?
 '\"	Start paragraph describing an argument to a library procedure.
 '\"	type is type of argument (int, etc.), in/out is either "in", "out",
 '\"	or "in/out" to describe whether procedure reads or modifies arg,
 '\"	and indent is equivalent to second arg of .IP (shouldn't ever be
 '\"	needed;  use .AS below instead)
 '\"
 '\" .AS ?type? ?name?
 '\"	Give maximum sizes of arguments for setting tab stops.  Type and
 '\"	name are examples of largest possible arguments that will be passed
 '\"	to .AP later.  If args are omitted, default tab stops are used.
 '\"
 '\" .BS
 '\"	Start box enclosure.  From here until next .BE, everything will be
 '\"	enclosed in one large box.
 '\"
 '\" .BE
 '\"	End of box enclosure.
 '\"
 '\" .CS
 '\"	Begin code excerpt.
 '\"
 '\" .CE
 '\"	End code excerpt.
 '\"
 '\" .VS ?version? ?br?
 '\"	Begin vertical sidebar, for use in marking newly-changed parts
 '\"	of man pages.  The first argument is ignored and used for recording
 '\"	the version when the .VS was added, so that the sidebars can be
 '\"	found and removed when they reach a certain age.  If another argument
 '\"	is present, then a line break is forced before starting the sidebar.
 '\"
 '\" .VE
 '\"	End of vertical sidebar.
 '\"
 '\" .DS
 '\"	Begin an indented unfilled display.
 '\"
 '\" .DE
 '\"	End of indented unfilled display.
 '\"
 '\" .SO
 '\"	Start of list of standard options for a Tk widget.  The
 '\"	options follow on successive lines, in four columns separated
 '\"	by tabs.
 '\"
 '\" .SE
 '\"	End of list of standard options for a Tk widget.
 '\"
 '\" .OP cmdName dbName dbClass
 '\"	Start of description of a specific option.  cmdName gives the
 '\"	option's name as specified in the class command, dbName gives
 '\"	the option's name in the option database, and dbClass gives
 '\"	the option's class in the option database.
 '\"
 '\" .UL arg1 arg2
 '\"	Print arg1 underlined, then print arg2 normally.

 .TH "Tcl_DumpActiveMemory" 3 8.1 Tcl "Tcl Library Procedures"
 .BS
 .SH NAME
 Tcl_DumpActiveMemory, Tcl_InitMemory, Tcl_ValidateAllMemory \- Validated memory allocation interface.
 .SH SYNOPSIS
 .nf
 \fB#include <tcl.h>\fR
 .sp
 int
 \fBTcl_DumpActiveMemory\fR(\fIfileName\fR)
 .sp
 void
 \fBTcl_InitMemory\fR(\fIinterp\fR)
 .sp
 void
 \fBTcl_ValidateAllMemory\fR(\fIfileName, line\fR)

 .SH ARGUMENTS
 .AP Tcl_Interp *interp in
 Tcl interpreter in which to add commands.
 .AP "CONST char" *fileName in
 For \fBTcl_DumpActiveMemory\fR, name of the file to which memory
 information will be written.  For \fBTcl_ValidateAllMemory\fR, name of
 the file from which the call is being made (normally \fB__FILE__\fR).
 .AP int line in
 Line number at which the call to \fBTcl_ValidateAllMemory\fR is made
 (normally \fB__LINE__\fR).
 .BE

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