      * The XML memory wrapper support 4 basic overloadable functions.

      * xmlFreeFunc:
      * @mem: an already allocated block of memory
      *
      * Signature for a free() implementation.

     d xmlFreeFunc     s               *   based(######typedef######)
     d                                     procptr

      * xmlMallocFunc:
      * @size:  the size requested in bytes
      *
      * Signature for a malloc() implementation.
      *
      * Returns a pointer to the newly allocated block or NULL in case of error.

     d xmlMallocFunc   s               *   based(######typedef######)
     d                                     procptr

      * xmlReallocFunc:
      * @mem: an already allocated block of memory
      * @size:  the new size requested in bytes
      *
      * Signature for a realloc() implementation.
      *
      * Returns a pointer to the newly reallocated block or NULL in case of error.

     d xmlReallocFunc  s               *   based(######typedef######)
     d                                     procptr

      * xmlStrdupFunc:
      * @str: a zero terminated string
      *
      * Signature for an strdup() implementation.
      *
      * Returns the copy of the string or NULL in case of error.

     d xmlStrdupFunc   s               *   based(######typedef######)

      * The 5 interfaces used for all memory handling within libxml.
      * Since indirect calls are only supported via a based prototype,
      *   storage is accessed via functions.
