-**
-** PURPOSE:
-**
-** MEMWATCH has been written to allow guys and gals that like to
-** program in C a public-domain memory error control product.
-** I hope you'll find it's as advanced as most commercial packages.
-** The idea is that you use it during the development phase and
-** then remove the MEMWATCH define to produce your final product.
-** MEMWATCH is distributed in source code form in order to allow
-** you to compile it for your platform with your own compiler.
-** It's aim is to be 100% ANSI C, but some compilers are more stingy
-** than others. If it doesn't compile without warnings, please mail
-** me the configuration of operating system and compiler you are using
-** along with a description of how to modify the source, and the version
-** number of MEMWATCH that you are using.

-**
-** To use, simply include 'MEMWATCH.H' as a header file,
-** and add MEMWATCH.C to your list of files, and define the macro
-** 'MEMWATCH'. If this is not defined, MEMWATCH will disable itself.
-**
-** To call the standard C malloc / realloc / calloc / free; use mwMalloc_(),
-** mwCalloc_() and mwFree_(). Note that mwFree_() will correctly
-** free both malloc()'d memory as well as mwMalloc()'d.
-**
-** 980317: C++ support has been disabled.
-** The code remains, but is not compiled.
-**
-** For use with C++, which allows use of inlining in header files
-** and class specific new/delete, you must also define 'new' as
-** 'mwNew' and 'delete' as 'mwDelete'. Do this *after* you include
-** C++ header files from libraries, otherwise you can mess up their
-** class definitions. If you don't define these, the C++ allocations
-** will not have source file and line number information. Also note,
-** most C++ class libraries implement their own C++ memory management,
-** and don't allow anyone to override them. MFC belongs to this crew.
-** In these cases, the only thing to do is to use MEMWATCH_NOCPP.
-**
-** You can capture output from MEMWATCH using mwSetOutFunc().
-** Just give it the adress of a "void myOutFunc(int c)" function,
-** and all characters to be output will be redirected there.
-**
-** A failing ASSERT() or VERIFY() will normally always abort your
-** program. This can be changed using mwSetAriFunc(). Give it a
-** pointer to a "int myAriFunc(const char *)" function. Your function
-** must ask the user whether to Abort, Retry or Ignore the trap.
-** Return 2 to Abort, 1 to Retry or 0 to Ignore. Beware retry; it
-** causes the expression to be evaluated again! MEMWATCH has a
-** default ARI handler. It's disabled by default, but you can enable
-** it by calling 'mwDefaultAri()'. Note that this will STILL abort
-** your program unless you define MEMWATCH_STDIO to allow MEMWATCH
-** to use the standard C I/O streams. Also, setting the ARI function
-** will cause MEMWATCH *NOT* to write the ARI error to stderr. The
-** error string is passed to the ARI function instead, as the
-** 'const char *' parameter.
-**
-** You can disable MEMWATCH's ASSERT/VERIFY and/or TRACE implementations.
-** This can be useful if you're using a debug terminal or smart debugger.
-** Disable them by defining MW_NOASSERT, MW_NOVERIFY or MW_NOTRACE.
-**
-** MEMWATCH fills all allocated memory with the byte 0xFE, so if
-** you're looking at erroneous data which are all 0xFE:s, the
-** data probably was not initialized by you. The exception is
-** calloc(), which will fill with zero's. All freed buffers are
-** zapped with 0xFD. If this is what you look at, you're using
-** data that has been freed. If this is the case, be aware that
-** MEMWATCH places a 'free'd block info' structure immediately
-** before the freed data. This block contains info about where
-** the block was freed. The information is in readable text,
-** in the format "FBI<counter>filename(line)", for example:
-** "FBI<267>test.c(12)". Using FBI's slows down free(), so it's
-** disabled by default. Use mwFreeBufferInfo(1) to enable it.
-**
-** To aid in tracking down wild pointer writes, MEMWATCH can perform
-** no-mans-land allocations. No-mans-land will contain the byte 0xFC.
-** MEMWATCH will, when this is enabled, convert recently free'd memory
-** into NML allocations.
-**
-** MEMWATCH protects it's own data buffers with checksums. If you
-** get an internal error, it means you're overwriting wildly,
-** or using an uninitialized pointer.
-**
-************************************************************************
-**
-** Note when compiling with Microsoft C:
-** - MSC ignores fflush() by default. This is overridden, so that
-** the disk log will always be current.
-**
-** This utility has been tested with:
-** PC-lint 7.0k, passed as 100% ANSI C compatible
-** Microsoft Visual C++ on Win16 and Win32
-** Microsoft C on DOS
-** SAS C on an Amiga 500
-** Gnu C on a PC running Red Hat Linux
-** ...and using an (to me) unknown compiler on an Atari machine.
-**
-************************************************************************
-**
-** Format of error messages in MEMWATCH.LOG:
-** message: <sequence-number> filename(linenumber), information
-**
-** Errors caught by MemWatch, when they are detected, and any
-** actions taken besides writing to the log file MEMWATCH.LOG:
-**
-** Double-freeing:
-** A pointer that was recently freed and has not since been
-** reused was freed again. The place where the previous free()
-** was executed is displayed.
-** Detect: delete or free() using the offending pointer.
-** Action: The delete or free() is cancelled, execution continues.
-** Underflow:
-** You have written just ahead of the allocated memory.
-** The size and place of the allocation is displayed.
-** Detect: delete or free() of the damaged buffer.
-** Action: The buffer is freed, but there may be secondary damage.
-** Overflow:
-** Like underflow, but you've written after the end of the buffer.
-** Detect: see Underflow.
-** Action: see Underflow.
-** WILD free:
-** An unrecognized pointer was passed to delete or free().
-** The pointer may have been returned from a library function;
-** in that case, use mwFree_() to force free() of it.
-** Also, this may be a double-free, but the previous free was
-** too long ago, causing MEMWATCH to 'forget' it.
-** Detect: delete or free() of the offending pointer.
-** Action: The delete or free() is cancelled, execution continues.
-** NULL free:
-** It's unclear to me whether or not freeing of NULL pointers
-** is legal in ANSI C, therefore a warning is written to the log file,
-** but the error counter remains the same. This is legal using C++,
-** so the warning does not appear with delete.
-** Detect: When you free(NULL).
-** Action: The free() is cancelled.
-** Failed:
-** A request to allocate memory failed. If the allocation is
-** small, this may be due to memory depletion, but is more likely
-** to be memory fragmentation problems. The amount of memory
-** allocated so far is displayed also.
-** Detect: When you new, malloc(), realloc() or calloc() memory.
-** Action: NULL is returned.
-** Realloc:
-** A request to re-allocate a memory buffer failed for reasons
-** other than out-of-memory. The specific reason is shown.
-** Detect: When you realloc()
-** Action: realloc() is cancelled, NULL is returned
-** Limit fail:
-** A request to allocate memory failed since it would violate
-** the limit set using mwLimit(). mwLimit() is used to stress-test
-** your code under simulated low memory conditions.
-** Detect: At new, malloc(), realloc() or calloc().
-** Action: NULL is returned.
-** Assert trap:
-** An ASSERT() failed. The ASSERT() macro works like C's assert()
-** macro/function, except that it's interactive. See your C manual.
-** Detect: On the ASSERT().
-** Action: Program ends with an advisory message to stderr, OR
-** Program writes the ASSERT to the log and continues, OR
-** Program asks Abort/Retry/Ignore? and takes that action.
-** Verify trap:
-** A VERIFY() failed. The VERIFY() macro works like ASSERT(),
-** but if MEMWATCH is not defined, it still evaluates the
-** expression, but it does not act upon the result.
-** Detect: On the VERIFY().
-** Action: Program ends with an advisory message to stderr, OR
-** Program writes the VERIFY to the log and continues, OR
-** Program asks Abort/Retry/Ignore? and takes that action.
-** Wild pointer:
-** A no-mans-land buffer has been written into. MEMWATCH can
-** allocate and distribute chunks of memory solely for the
-** purpose of trying to catch random writes into memory.
-** Detect: Always on CHECK(), but can be detected in several places.
-** Action: The error is logged, and if an ARI handler is installed,
-** it is executed, otherwise, execution continues.
-** Unfreed:
-** A memory buffer you allocated has not been freed.
-** You are informed where it was allocated, and whether any
-** over or underflow has occured. MemWatch also displays up to
-** 16 bytes of the data, as much as it can, in hex and text.
-** Detect: When MemWatch terminates.
-** Action: The buffer is freed.
-** Check:
-** An error was detected during a CHECK() operation.
-** The associated pointer is displayed along with
-** the file and line where the CHECK() was executed.
-** Followed immediately by a normal error message.
-** Detect: When you CHECK()
-** Action: Depends on the error
-** Relink:
-** After a MEMWATCH internal control block has been trashed,
-** MEMWATCH tries to repair the damage. If successful, program
-** execution will continue instead of aborting. Some information
-** about the block may be gone permanently, though.
-** Detect: N/A
-** Action: Relink successful: program continues.
-** Relink fails: program aborts.
-** Internal:
-** An internal error is flagged by MEMWATCH when it's control
-** structures have been damaged. You are likely using an uninitialized
-** pointer somewhere in your program, or are zapping memory all over.
-** The message may give you additional diagnostic information.
-** If possible, MEMWATCH will recover and continue execution.
-** Detect: Various actions.
-** Action: Whatever is needed
-** Mark:
-** The program terminated without umarking all marked pointers. Marking
-** can be used to track resources other than memory. mwMark(pointer,text,...)
-** when the resource is allocated, and mwUnmark(pointer) when it's freed.
-** The 'text' is displayed for still marked pointers when the program
-** ends.
-** Detect: When MemWatch terminates.
-** Action: The error is logged.

-** - mwInit() can be called to disable the atexit() usage. If mwInit()
-** is called directly, you must call mwTerm() to end MemWatch, or
-** mwAbort().
-** - mwTerm() is usually not nessecary to call; but if called, it will
-** call mwAbort() if it finds that it is cancelling the 'topmost'
-** mwInit() call.
-** - mwAbort() cleans up after MEMWATCH, reports unfreed buffers, etc.

-/*
-** Setup functions
-** These functions control the operation of MEMWATCH's protective features.
-** - mwFlushNow() causes MEMWATCH to flush it's buffers.
-** - mwDoFlush() controls whether MEMWATCH flushes the disk buffers after
-** writes. The default is smart flushing: MEMWATCH will not flush buffers
-** explicitly until memory errors are detected. Then, all writes are
-** flushed until program end or mwDoFlush(0) is called.
-** - mwLimit() sets the allocation limit, an arbitrary limit on how much
-** memory your program may allocate in bytes. Used to stress-test app.
-** Also, in virtual-memory or multitasking environs, puts a limit on
-** how much MW_NML_ALL can eat up.
-** - mwGrab() grabs up X kilobytes of memory. Allocates actual memory,
-** can be used to stress test app & OS both.
-** - mwDrop() drops X kilobytes of grabbed memory.
-** - mwNoMansLand() sets the behaviour of the NML logic. See the
-** MW_NML_xxx for more information. The default is MW_NML_DEFAULT.
-** - mwStatistics() sets the behaviour of the statistics collector. See
-** the MW_STAT_xxx defines for more information. Default MW_STAT_DEFAULT.
-** - mwFreeBufferInfo() enables or disables the tagging of free'd buffers
-** with freeing information. This information is written in text form,
-** using sprintf(), so it's pretty slow. Disabled by default.
-** - mwAutoCheck() performs a CHECK() operation whenever a MemWatch function
-** is used. Slows down performance, of course.
-** - mwCalcCheck() calculates checksums for all data buffers. Slow!
-** - mwDumpCheck() logs buffers where stored & calc'd checksums differ. Slow!!
-** - mwMark() sets a generic marker. Returns the pointer given.
-** - mwUnmark() removes a generic marker. If, at the end of execution, some
-** markers are still in existence, these will be reported as leakage.
-** returns the pointer given.

-** Testing/verification/tracing
-** All of these macros except VERIFY() evaluates to a null statement

-** - mwIsReadAddr() checks a memory area for read privilige.
-** - mwIsSafeAddr() checks a memory area for both read & write privilige.
-** This function and mwIsReadAddr() is highly system-specific and
-** may not be implemented. If this is the case, they will default
-** to returning nonzero for any non-NULL pointer.
-** - CHECK() does a complete memory integrity test. Slow!
-** - CHECK_THIS() checks only selected components.
-** - CHECK_BUFFER() checks the indicated buffer for errors.
-** - mwASSERT() or ASSERT() If the expression evaluates to nonzero, execution continues.
-** Otherwise, the ARI handler is called, if present. If not present,
-** the default ARI action is taken (set with mwSetAriAction()).
-** ASSERT() can be disabled by defining MW_NOASSERT.
-** - mwVERIFY() or VERIFY() works just like ASSERT(), but when compiling without
-** MEMWATCH the macro evaluates to the expression.
-** VERIFY() can be disabled by defining MW_NOVERIFY.
-** - mwTRACE() or TRACE() writes some text and data to the log. Use like printf().

-** Specifying NULL will direct output to the log file.
-** - mwSetAriFunc() gives MEMWATCH the adress of a function to call

-** action specified by mwSetAriAction().

-** use if no ARI handler is specified. Defaults to MW_ARI_ABORT.
-** - mwAriHandler() is an ANSI ARI handler you can use if you like. It
-** dumps output to stderr, and expects input from stdin.

-** C++ support section
-** Implements the C++ support. Please note that in order to avoid
-** messing up library classes, C++ support is disabled by default.
-** You must NOT enable it until AFTER the inclusion of all header
-** files belonging to code that are not compiled with MEMWATCH, and
-** possibly for some that are! The reason for this is that a C++
-** class may implement it's own new() function, and the preprocessor
-** would substitute this crucial declaration for MEMWATCH new().
-** You can forcibly deny C++ support by defining MEMWATCH_NOCPP.
-** To enble C++ support, you must be compiling C++, MEMWATCH must
-** be defined, MEMWATCH_NOCPP must not be defined, and finally,
-** you must define 'new' to be 'mwNew', and 'delete' to be 'mwDelete'.
-** Unlike C, C++ code can begin executing *way* before main(), for
-** example if a global variable is created. For this reason, you can
-** declare a global variable of the class 'MemWatch'. If this is
-** is the first variable created, it will then check ALL C++ allocations
-** and deallocations. Unfortunately, this evaluation order is not
-** guaranteed by C++, though the compilers I've tried evaluates them
-** in the order encountered.
