// Provides a bidirectional "pipe" abstraction that is portable

//
// = DESCRIPTION
// Uses "name" for lookup in the ACE service repository. Obtains
// the object and returns it as the appropriate type.
public:
// = Initialization and termination.
ACE_Pipe (void);
// Default constructor (does nothing...).

// Default dtor. It doesn't close the handles for you.
int open (ACE_HANDLE handles[2]);
// Open the pipe and initialize the handles.
int open (int buffer_size = ACE_DEFAULT_MAX_SOCKET_BUFSIZ);
// Open the pipe, setting the buffer size to the maximum.
int close (void);
// Close down the pipe HANDLEs;
// = Accessors.

// bi-directional.
void dump (void) const;
