**
** Include File: LYLeaks.h
** Purpose: Header to convert requests for allocation to Lynx
** custom functions to track memory leaks.
** Remarks/Portability/Dependencies/Restrictions:
** For the stdlib.h allocation functions to be overriden by the
** Lynx memory tracking functions all modules allocating,
** freeing, or resizing memory must have LY_FIND_LEAKS
** defined before including this file.
** This header file should be included in every source file which
** does any memory manipulation through use of the
** stdlib.h memory functions.
** For proper reporting of memory leaks, the function LYLeaks
** should be registered for execution by atexit as the
** very first executable statement in main.
** This code is slow and should not be used except in debugging
** circumstances (don't define LY_FIND_LEAKS).
** If you are using LY_FIND_LEAKS and don't want the LYLeak*
** memory functions to be used in a certain file,
** define NO_MEMORY_TRACKING before including this file.
** The only safe way to call the LYLeak* functions is to use
** the below macros because they depend on the static
** string created by __FILE__ to not be dynamic in
** nature (don't free it and assume will exist at all
** times during execution).
** Revision History:
** 05-26-94 created for Lynx 2-3-1, Garrett Arch Blythe
** 10-30-97 modifed to handle StrAllocCopy() and
** StrAllocCat(). - KW & FM
