-#if !defined( MEMORY_INCLUDED ) /* Include this file only once */
-#define MEMORY_INCLUDED
-/*
-*+
-* Name:
-* memory.h
-
-* Purpose:
-* Define the interface to the Memory module.
-
-* Description:
-* This module defines functions which wrap up and extend the
-* standard C functions for performing memory allocation. They
-* provide better security against memory leaks, etc., and should
-* not be inter-mixed with the standard C functions.
-*
-* Note that this module is not a class implementation, although it
-* resembles one.
-
-* Functions Defined:
-* Public:
-* None.
-*
-* Protected:
-* astAppendString
-* Append a string to another string which grows dynamically.
-* astCalloc
-* Allocate memory.
-* astChrMatch
-* Case-insensitive string comparison.
-* astChrMatchN
-* Case-insensitive string comparison of an most N characters.
-* astFree
-* Free previously allocated memory.
-* astGrow
-* Allocate memory for an adjustable array.
-* astMalloc
-* Allocate memory.
-* astRealloc
-* Change the size of a dynamically allocated region of memory.
-* astSizeOf
-* Determine the size of a dynamically allocated region of memory.
-* astStore
-* Store data in dynamically allocated memory.
-* astString
-* Create a C string from an array of characters.
-* astStringArray
-* Create an array of C strings from an array of characters.
-* astStringCase
-* Convert a string to upper or lower case.
-* astChrLen
-* Returns length of a string without trailing white space, etc.
-* astChrTrunc
-* Terminate a string to exclude trailing spaces.
-* astSscanf
-* Like sscanf, but fixes certain platform-specific bugs in the
-* native sscanf implementation.
-* astTSizeOf
-* Determine the total size of a dynamically allocated region of memory.

-
-* History:
-* 8-JAN-1996 (RFWS):
-* Original version.
-* 26-JAN-1996 (RFWS)
-* Added function interfaces.
-* 20-JUN-1996 (RFWS):
-* Added astString.
-* 15-JUL-1996 (RFWS):
-* Use improved prologue style, etc. and make all functions protected.
-* 11-SEP-1996 (RFWS):
-* Added astStringArray (original written by DSB).
-* 18-MAR-1998 (RFWS):
-* Make interface available for writing foreign language and
-* graphics interfaces, etc.
-* 18-MAR-1998 (RFWS):
-* Added explicit arguments to function macros.
-* 29-JAN-2002 (DSB):
-* Added astChrLen and astSscanf.
-* 15-NOV-2002 (DSB):
-* Added astChrMatch astChrMatchN.
-* 23-FEB-2006 (DSB):
-* Added astMemCaching and AST__TUNULL.
-* 2-MAR-2006 (DSB):
-* Only use astSscanf if the system on which AST was configured
-* showed the non-ANSI behaviour reported by Bill Joye.
-* 27-JUN-2007 (DSB):
-* Added astIsDynamic.
-* 25-OCT-2007 (DSB):
-* Added astRemoveLeadingBlanks.
-* 22-FEB-2008 (DSB):
-* Added astChrSub.
-* 19-MAY-2010 (DSB):
