/** @file tidy.h - Defines HTML Tidy API implemented by tidy library.

  Public interface is const-correct and doesn't explicitly depend
  on any globals.  Thus, thread-safety may be introduced w/out
  changing the interface.

  Looking ahead to a C++ wrapper, C functions always pass 
  this-equivalent as 1st arg.

/** @defgroup Memory  Memory Allocation
**
** Tidy uses a user provided allocator for all
** memory allocations.  If this allocator is
** not provided, then a default allocator is
** used which simply wraps standard C malloc/free
** calls.  These wrappers call the panic function
** upon any failure.  The default panic function
** prints an out of memory message to stderr, and
** calls exit(2).
**
** For applications in which it is unacceptable to
** abort in the case of memory allocation, then the
** panic function can be replaced with one which
** longjmps() out of the tidy code.  For this to
** clean up completely, you should be careful not
** to use any tidy methods that open files as these
** will not be closed before panic() is called.
**
** TODO: associate file handles with tidyDoc and
** ensure that tidyDocRelease() can close them all.
**
** Calling the withAllocator() family (
** tidyCreateWithAllocator, tidyBufInitWithAllocator,
** tidyBufAllocWithAllocator) allow settings custom
** allocators).
**
** All parts of the document use the same allocator.
** Calls that require a user provided buffer can
** optionally use a different allocator.
**
** For reference in designing a plug-in allocator,
** most allocations made by tidy are less than 100
** bytes, corresponding to attribute names/values, etc.
**
** There is also an additional class of much larger
** allocations which are where most of the data from
** the lexer is stored.  (It is not currently possible
** to use a separate allocator for the lexer, this
** would be a useful extension).
**
** In general, approximately 1/3rd of the memory
** used by tidy is freed during the parse, so if
** memory usage is an issue then an allocator that 
** can reuse this memory is a good idea.

    The vtbl itself can reside in static/global data, and hence does not
    need to be initialised each time an allocator is created, and furthermore
    the memory is shared amongst all created allocators.
