PFStream
===============

A stream is sequence of bytes. Small streams (<256K) reside in memory, and large streams are flushed to temporary files. These files are created in a folder specified during initializing the library. If the library is not initialized during creating a stream, the files are created in a temporary folder.

.. cpp:function:: tStreamPos seek(tStreamPos offset, int origin);

	:param offset: Offset from origin 
	:param origin: FILE_BEGIN, FILE_CURRENT or FILE_END
	:description: Moves the stream pointer to a specified location. 

.. cpp:function:: tStreamSize read(void * buffer, tStreamSize size);

	:param buffer: Pointer to data buffer 
	:param size: Size of buffer
	:description: Reads data from a stream and returns the number of bytes actually read. 

.. cpp:function:: tStreamSize write(const void * buffer, tStreamSize size);

	:param buffer: Pointer to data buffer 
	:param size: Size of buffer
	:description: Writes data to a stream and returns the number of bytes actually written. 

.. cpp:function:: tStreamPos size();

	:description: Returns number of bytes in stream.

.. cpp:function:: tStreamPos copyTo(PFStream * pStream);

	:description: Copies stream contents to another stream.

.. cpp:function:: tStreamPos setEndOfStream();

	:description: Set the stream end at the current position.

.. cpp:function:: void reset();

	:description: Clear the stream contents.
