Detailed Description

Abstract base class for UNIX FIFOs.

UNIX FIFOs are also known Named Pipes, which are totally unrelated to Windows Named Pipes. If you want to use a local IPC mechanism that will be portable to both UNIX and Windows, take a look at the ACE_Pipe or ACE_SPIPE_Stream classes.

Constructor & Destructor Documentation

ACE_FIFO::ACE_FIFO ( void ) [protected]

Default constructor.

Protected constructors ensure this class cannot be used directly. User code must use ACE_FIFO_Send and/or ACE_FIFO_Recv.

ACE_FIFO::ACE_FIFO	(	const ACE_TCHAR *	rendezvous,
		int	flags,
		mode_t	perms,
		LPSECURITY_ATTRIBUTES	sa = `0`
	)		`[protected]`

Open up the named pipe on the rendezvous in accordance with the flags.

Member Function Documentation

int ACE_FIFO::close ( void )

Close down the ACE_FIFO without removing the rendezvous point.

Reimplemented in ACE_FIFO_Recv.

void ACE_FIFO::dump ( void ) const

Dump the state of an object.

Reimplemented from ACE_IPC_SAP.

Reimplemented in ACE_FIFO_Recv_Msg, ACE_FIFO_Recv, ACE_FIFO_Send_Msg, and ACE_FIFO_Send.

int ACE_FIFO::get_local_addr ( const ACE_TCHAR *& rendezvous ) const [inline]

Return the local address of this endpoint.

int ACE_FIFO::open	(	const ACE_TCHAR *	rendezvous,
		int	flags,
		mode_t	perms,
		LPSECURITY_ATTRIBUTES	sa = `0`
	)

Open up the named pipe (FIFO) on the rendezvous point in accordance with the flags.

If flags contains O_CREAT open() will attempt to call mkfifo() to create the FIFO before opening it. In this case, this method will not fail simply because the fifo already exists.

Return values:
