Constructor & Destructor Documentation

DcmOutputBufferStream::DcmOutputBufferStream (  void *  buf,
Uint32  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.

Member Function Documentation

virtual void DcmOutputBufferStream::flushBuffer (  void *&  buffer,
Uint32 &  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
