Detailed Description

Simple stream interface

Member Function Documentation

virtual signed int ISimpleStream::AskInterface ( const BGUID *  piid, struct IRoot **  ppr  )

pure virtual

ask object for another interface

Implements IRoot.

virtual signed int ISimpleStream::DecRef ( )

pure virtual

decrements the reference count for the object

Implements IRoot.

virtual signed int ISimpleStream::Flush ( )

pure virtual

If the output stream on this stream is buffered, this function will ensure that all currently written data is applied to the stream.

virtual signed int ISimpleStream::IncRef ( )

pure virtual

increments the reference count for the object

Implements IRoot.

virtual signed int ISimpleStream::Peek ( )

pure virtual

Returns S_OK if no more data available to read on the stream, E_FAIL if there is more data available. You may use Peek calls to ensure that client/server calls are in sync.

virtual signed int ISimpleStream::ReadWrite ( bool  breadwrite, void *  pbuf, h_uint32  sz, h_uint32 *  sze  )

pure virtual

Parameters

breadwrite	– if equal to true the function performs read operations, otherwise performs write operation
pbuf	– pointer to buffer or data to be read into or written
sz	– size of the buffer or data
sze	– amount of data read or written
