    public class SmbNamedPipe

extends SmbFile

This class will allow a Java program to read and write data to Named Pipes and Transact NamedPipes.

There are three Win32 function calls provided by the Windows SDK that are important in the context of using jCIFS. They are:

- `CallNamedPipe` A message-type pipe call that opens, writes to, reads from, and closes the pipe in a single operation.
- `TransactNamedPipe` A message-type pipe call that writes to and reads from an existing pipe descriptor in one operation.
- `CreateFile`, `ReadFile`, `WriteFile`, and `CloseFile` A byte-type pipe can be opened, written to, read from and closed using the standard Win32 file operations.

The jCIFS API maps all of these operations into the standard Java `XxxputStream` interface. A special `PIPE_TYPE` flags is necessary to distinguish which type of Named Pipe behavior is desired.

`SmbNamedPipe` Constructor Examples
Code Sample | Description

     new SmbNamedPipe( "smb://server/IPC$/PIPE/foo",
             SmbNamedPipe.PIPE_TYPE_RDWR |
             SmbNamedPipe.PIPE_TYPE_CALL );

Open the Named Pipe foo for reading and writing. The pipe will behave like the `CallNamedPipe` interface.

     new SmbNamedPipe( "smb://server/IPC$/foo",
             SmbNamedPipe.PIPE_TYPE_RDWR |
             SmbNamedPipe.PIPE_TYPE_TRANSACT );

Open the Named Pipe foo for reading and writing. The pipe will behave like the `TransactNamedPipe` interface.

     new SmbNamedPipe( "smb://server/IPC$/foo",
             SmbNamedPipe.PIPE_TYPE_RDWR );

Open the Named Pipe foo for reading and writing. The pipe will behave as though the `CreateFile`, `ReadFile`, `WriteFile`, and `CloseFile` interface was being used.

See Using jCIFS to Connect to Win32 Named Pipes for a detailed description of how to use jCIFS with Win32 Named Pipe server processes.

Constructor Detail

### SmbNamedPipe

    public SmbNamedPipe(java.lang.String url,
                        int pipeType)
                 throws java.net.MalformedURLException,
                        java.net.UnknownHostException

  Open the Named Pipe resource specified by the url parameter. The pipeType parameter should be at least one of the `PIPE_TYPE` flags combined with the bitwise OR operator `|`. See the examples listed above.

  Throws:
    `java.net.MalformedURLException`
    `java.net.UnknownHostException`

### SmbNamedPipe

    public SmbNamedPipe(java.lang.String url,
                        int pipeType,

                 throws java.net.MalformedURLException,

Throws:

Method Detail

### getNamedPipeInputStream

    public java.io.InputStream getNamedPipeInputStream()
                                                throws java.io.IOException

  Return the `InputStream` used to read information from this pipe instance. Presumably data would first be written to the `OutputStream` associated with this Named Pipe instance although this is not a requirement (e.g. a read-only named pipe would write data to this stream on connection). Reading from this stream may block. Therefore it may be necessary that an addition thread be used to read and write to a Named Pipe.

  Throws:
    `java.io.IOException`

### getNamedPipeOutputStream

    public java.io.OutputStream getNamedPipeOutputStream()
                                                  throws java.io.IOException

  Return the `OutputStream` used to write information to this pipe instance. The act of writing data to this stream will result in response data recieved in the `InputStream` associated with this Named Pipe instance (unless of course it does not elicite a response or the pipe is write-only).

  Throws:
    `java.io.IOException`
