/* =====================================================================   File:	rmalloc.h   Author:	Rammi   Date:	11/16/1995   Reminder:	Use at your own risk.   Content:	Switching on/off of malloc debug library. This is done 		by preprocessor switch MALLOC_DEBUG.		If MALLOC_DEBUG is defined, special debug versions for		the functions of the standard malloc lib are used.		They try to get hold of the following things:		* Overwrite borders of allocated block		* Multiple free of a block		* free of an unallocated block		All sources must include this file. No more changes necessary.		Special macros:		RM_TEST      Force testing of all allocated blocks.		RM_STAT      Show a statistic of allocated blocks.		RM_RETAG(p)  change position for allocated block to pos of			     this macro			     		RM_SET(p, f) Set flag f for block p. f can be a combination of 			     the following:		   RM_STATIC Block is considered static. Is only summarized                             in statistics.			     		   RM_STRING Block is meant to hold a string.		The global behaviour can be changed by editing, recompiling and		linking rmalloc.c. See information there.		   Changes:	                See rmalloc.c   ===================================================================== */#ifndef R_MALLOC_H#define R_MALLOC_H//#define ALLOW_OS_CODE/* =========   INCLUDEs:   ========= */   #include <stdlib.h>#include <string.h>#include "rmdef/rmdef.h"/* ========   DEFINEs:   ======== *//* #define RM_UPPERSTYLE */	/* this is only used for backward compatibility *//* once again useful: INT2STRING(prepro_macro_containing_number)-->"number" */#define FUNCTIONIZE(a,b)  a(b) #define STRINGIZE(a)      #a#define INT2STRING(i)     FUNCTIONIZE(STRINGIZE,i)/* Flags in header (with WITH_FLAGS defined, see rmalloc.c) */#define RM_STATIC         (0x0001 << 0)         /* static memory */#define RM_STRING         (0x0001 << 1)         /* contains string */#define RM_UPPERSTYLE#define MALLOC_DEBUG                #ifdef MALLOC_DEBUG/* Useful, to build 1 string from __FILE__ & __LINE__ in compile time: */#define RM_FILE_POS       __FILE__ ":" INT2STRING(__LINE__) //RM_EXTERN_C_BLOCKSTART#if defined(MALLOC_DEBUG) || defined(RM_NEED_PROTOTYPES)void *Rmalloc(size_t size, const char *file);void *Rcalloc(size_t nelem, size_t size, const char *file);void *Rrealloc(void *p, size_t size, const char *file);void  Rfree(void *p, const char *file);char *Rstrdup(const char *str, const char *file);char *Rgetcwd(char *buffer, size_t size, const char *file);void  Rtest_malloc(const char *file);void  Rmalloc_test(const char *file);void  Rmalloc_stat(const char *file);void *Rmalloc_retag(void *p, const char *file);void *Rmalloc_set_flags(void *p, RMuint32 flags, const RMascii *file);#endif /* MALLOC_DEBUG || RM_NEED_PROTOTYPES *///RM_EXTERN_C_BLOCKEND#ifdef RM_UPPERSTYLE/* Deprecated: Only used for backward compatibility: */#  define MALLOC(s)       Rmalloc((s), RM_FILE_POS)#  define CALLOC(n,s)     Rcalloc((n), (s), RM_FILE_POS)#  define REALLOC(p,s)    Rrealloc((p), (s), RM_FILE_POS)#  define RFREE(p)         Rfree((p), RM_FILE_POS)#  define FREE0(p)        Rfree((p), RM_FILE_POS),(p)=NULL#  define STRDUP(s)       Rstrdup((s), RM_FILE_POS)#else /* !RM_UPPERSTYLE *//* Wrap with our stuff: */#  define malloc(s)       Rmalloc((s), RM_FILE_POS)#  define calloc(n,s)     Rcalloc((n), (s), RM_FILE_POS)#  define realloc(p,s)    Rrealloc((p), (s), RM_FILE_POS)#  define free(p)         Rfree((p), RM_FILE_POS)#  define free0(p)        Rfree((p), RM_FILE_POS),(p)=NULL#  define strdup(s)       Rstrdup((s), RM_FILE_POS)#  define getcwd(b,s)	  Rgetcwd((b), (s), RM_FILE_POS)#endif /* RM_UPPERSTYLE */#define RM_TEST           Rmalloc_test(RM_FILE_POS)#define RM_STAT           Rmalloc_stat(RM_FILE_POS)#define RM_RETAG(p)       Rmalloc_retag((p), RM_FILE_POS)#define RM_SET(p, f)      Rmalloc_set_flags((p), (f), RM_FILE_POS)#else /* !
