NAME
       KVMAllocator - KVMAllocator is a virtual memory allocator.


SYNOPSIS
       #include <kvmallocator.h>

   Public Member Functions
       KVMAllocator ()
           Create a KVMAllocator.
       ~KVMAllocator ()
           Destruct the KVMAllocator and release all memory.
       Block * allocate (size_t _size)
           Allocate a virtual memory block.
       void free (Block *block)
           Free a virtual memory block.
       void copy (void *dest, Block *src, int _offset=0, size_t length=0)
           Copy length bytes from _offset in the virtual memory block src to
           normal memory at address *dest.
       void copy (Block *dest, void *src, int _offset=0, size_t length=0)
           Copy length bytes from normal memory at address src to _offset in
           the virtual memory block dest.
       void * map (Block *block)

       void unmap (Block *block)
           Unmap a virtual memory block.

Detailed Description
       KVMAllocator is a virtual memory allocator.

       Memory is allocated block-wise in a tmp file.
