virtual void Release() = 0;

Releases chunk file interface.

virtual void ReleaseMemoryBuffer() = 0;

Releases memory that was allocated in WriteToMemoryBuffer()

virtual bool Write(const char * filename) = 0;

Writes chunks to file.

virtual bool WriteToMemoryBuffer(void ** pData, int * nSize) = 0;

Writes chunks to a memory buffer (allocated inside) and returns pointer to the allocated memory (pData) and its size (nSize). The memory will be released on destruction of the ChunkFile object, or on the next WriteToMemoryBuffer() call, or on ReleaseMemoryBuffer() call.
