NAME

ACE_Pipe - Provides a bidirectional "pipe" abstraction that is portable to Windows NT, SVR4 UNIX, and BSD UNIX.

SYNOPSIS

#include <ace/Pipe.h>
class ACE_Pipe
{
  public:
    ACE_Pipe (void);
    ACE_Pipe (ACE_HANDLE handles[2]);
    ACE_Pipe (ACE_HANDLE read, ACE_HANDLE write);
    ~ACE_Pipe (void);
    int open (ACE_HANDLE handles[2]);
    int open (int buffer_size = ACE_DEFAULT_MAX_SOCKET_BUFSIZ);
    int close (void);
    ACE_HANDLE read_handle (void) const;
    ACE_HANDLE write_handle (void) const;
    void dump (void) const;
  private:
    ACE_HANDLE handles_[2];
};

DESCRIPTION

Uses "name" for lookup in the ACE service repository. Obtains the object and returns it as the appropriate type.

Initialization and termination.

ACE_Pipe (void);

Default constructor (does nothing...).

ACE_Pipe (ACE_HANDLE handles[2]);

Open the pipe and initialize the handles.

ACE_Pipe (ACE_HANDLE read, ACE_HANDLE write);

Initialize the ACE_Pipe from the read and write handles.

~ACE_Pipe (void);

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.

ACE_HANDLE read_handle (void) const;

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.

ACE_HANDLE write_handle (void) const;

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.
