// = TITLE
// Provides a bidirectional "pipe" abstraction that is portable
// to Windows NT, SVR4 UNIX, and BSD UNIX.
//
// = 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...).

// Open the pipe and initialize the handles.

// Initialize the <ACE_Pipe> from the <read> and <write> handles.
int open (ACE_HANDLE handles[2]);
// Open the pipe and initialize the handles.
int open (void);
// Open the pipe.
int close (void);
// Close down the pipe HANDLEs;
// = Accessors.

// This is the "read" side of the pipe. Note, however, that
// processes can also write to this handle as well since pipes are
// bi-directional.

// This is the "write" side of the pipe. Note, however, that
// processes can also read to this handle as well since pipes are
// bi-directional.
void dump (void) const;
// Dump the state of the object.
