Class `RSmsSocketBuf`

class RSmsSocketBuf : public TStreamBuf;

Support

Supported from 6.1

Description

An SMS stream buffer to read and write over a socket.

Derivation

`MStreamBuf`	A stream buffer that provides a generic I/O interface for streamed data
`RSmsSocketBuf`	An SMS stream buffer to read and write over a socket
`TStreamBuf`	Adds buffering capabilities to a stream buffer

Defined in RSmsSocketBuf:
DoSynchL(), Lag(), Lag(), OverflowL(), RSmsSocketBuf(), SocketWriteL(), UnderflowL(), iBuffer, iSocket

Inherited from MStreamBuf:
Close(), DoRelease(), DoSeekL(), ERead, EWrite, PushL(), Read(), ReadL(), Release(), SeekL(), SizeL(), Synch(), SynchL(), TMark, TRead, TWrite, TellL(), Write(), WriteL()

Inherited from TStreamBuf:
Avail(), DoReadL(), DoWriteL(), End(), Ptr(), SetBuf(), SetEnd(), SetPtr(), TArea

Member functions

`UnderflowL()`

private: TInt UnderflowL(TInt aMaxLength);

Description

Fills the buffer's read area from the socket.

The function panics if the socket is not readable.

Parameters

TInt aMaxLength

Unused

Return value


TInt

The length of the buffer

Leave codes

Socket read errors

`OverflowL()`

private: void OverflowL();

Description

Empties the buffer and sets up the buffer's write area.

The function panics if the socket is not writable.

`DoSynchL()`

private: void DoSynchL();

Description

Synchronises the stream buffer with the stream, leaving if any error occurs.
