Detailed Description

output stream that writes into a buffer of fixed length which must be provided by the caller.

Constructor & Destructor Documentation

DcmOutputBufferStream::DcmOutputBufferStream	(	void *	buf,
		offile_off_t	bufLen
	)

constructor

Parameters:

buf	buffer in which data is stored. Must be allocated by caller and remain valid during the lifetime of this object.
bufLen	buffer length, must be even number > 0.

virtual void DcmOutputBufferStream::flushBuffer	(	void *&	buffer,
		offile_off_t &	length
	)		`[virtual]`

retrieves and flushes the underlying buffer.

After return of this method, the buffer is considered to have been flushed (copied, stored) by the caller and is reused by the next write operation.

Parameters:

buffer	pointer to user provided buffer returned in this parameter
length	number of bytes in buffer returned in this parameter
