Detailed Description

Defines the member functions for the base class of the ACE_SPIPE abstraction.

ACE_SPIPE was designed as a wrapper facade for STREAM pipes. On Windows, however, ACE_SPIPE is a wrapper for Named Pipes. Therefore, on Windows, it is better to use the ACE_Proactor or blocking operations in lieu of using the ACE_Reactor.

See also:: ACE_SPIPE_Acceptor for additional notes on use with ACE_Reactor on Windows.

Warning:: Windows: Works only on Windows NT 4 and higher.
Works on non-Windows platforms only when ACE_HAS_STREAM_PIPES is defined.

Constructor & Destructor Documentation

ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_SPIPE::ACE_SPIPE ( void ) [protected]

Ensure that this class is an abstract base class.

Member Function Documentation

int ACE_SPIPE::close ( void )

Close down the SPIPE without removing the rendezvous point.

Closes the underlying pipe handle and sets this object's handle value to ACE_INVALID_HANDLE.

Returns:: 0 for success; -1 for failure. If a failure occurs, further error information is available from ACE_OS::last_error().

Reimplemented in ACE_SPIPE_Acceptor, ACE_UPIPE_Acceptor, and ACE_UPIPE_Stream.

ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_INLINE int ACE_SPIPE::disable ( int signum ) const

Disable signal

signum.
Note:
This reimplements the inherited method from ACE_IPC_SAP. Since the signal actions do not make any sense on Windows, this method intercepts the call and NOPs it. On non-Windows, it is passed through to ACE_IPC_SAP::disable().

Reimplemented from ACE_IPC_SAP.

void ACE_SPIPE::dump ( void ) const

Dump the state of an object.

Reimplemented from ACE_IPC_SAP.

Reimplemented in ACE_SPIPE_Acceptor, ACE_SPIPE_Stream, ACE_UPIPE_Acceptor, and ACE_UPIPE_Stream.

int ACE_SPIPE::get_local_addr ( ACE_SPIPE_Addr & ) const

Return the local address of this endpoint.

Returns the local address of the SPIPE's endpoint in
