virtual void tnbufstream::close (  void   )  [inline, protected, virtual]

Definition at line 42 of file simplestream.h. Referenced by tn_file_buf_stream::~tn_file_buf_stream(), and tn_lzw_file_buf_stream::~tn_lzw_file_buf_stream().

virtual void tnbufstream::readbuffer (  void   )  [protected, pure virtual]

Implemented in tn_file_buf_stream. Referenced by readdata().

int tnbufstream::readdata (  void *  buf, int  size, bool  excpt = true )  [virtual]

Reads data from the stream. Parameters: buf  the buffer which the data is written to size  the number of bytes which should be read excpt  If true the operation will throw an exception if the desired number of bytes cannot be read. Returns: the number of bytes which were read. Implements tnstream. Reimplemented in tn_lzw_file_buf_stream.

void tnbufstream::writedata (  const void *  buf, int  size )  [virtual]

writes data to the stream Parameters: buf  pointer to the buffer size  the number of bytes which are going to be written Implements tnstream. Reimplemented in tn_lzw_file_buf_stream.
