NAME
       Tcl_DumpActiveMemory, Tcl_InitMemory, Tcl_ValidateAllMemory - Validated
       memory allocation interface.

SYNOPSIS
       #include <tcl.h>

       int
       Tcl_DumpActiveMemory(fileName)

       void
       Tcl_InitMemory(interp)

       void
       Tcl_ValidateAllMemory(fileName, line)


ARGUMENTS
       Tcl_Interp   *interp            (in)      Tcl interpreter in  which  to
                                                 add commands.

       char         *fileName          (in)      For     Tcl_DumpActiveMemory,
                                                 name of  the  file  to  which
                                                 memory  information  will  be
                                                 written.     For    Tcl_Vali-
                                                 dateAllMemory,  name  of  the
                                                 file from which the  call  is
                                                 being      made     (normally
                                                 __FILE__).

       int          line               (in)      Line number at which the call
                                                 to  Tcl_ValidateAllMemory  is
                                                 made (normally __LINE__).

DESCRIPTION
       These functions provide access to  Tcl  memory  debugging  information.
       They  are  only available when Tcl has been compiled with TCL_MEM_DEBUG
       defined at compile-time.

       Tcl_DumpActiveMemory will output a list of all currently allocated mem-
       ory  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 ckalloc was called to allocate the block
       and line number  in  that  file.   It  is  especially  useful  to  call
       Tcl_DumpActiveMemory after the Tcl interpreter has been deleted.

       Tcl_InitMemory  adds the Tcl memory command to the interpreter given by
       interp.  It is called by Tcl_Main  when  Tcl  has  been  compiled  with
       TCL_MEM_DEBUG defined.

       Tcl_ValidateAllMemory  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 ckalloc  and  ckfree  are  called.
       This function forces the validation to occur at any point.
