Variables

var ErrClosed = PipeError{"Pipe has been closed.", false}

ErrClosed is the error returned by PipeListener.Accept when Close is called on the PipeListener.

Functions

func NewIpcClient

func NewIpcClient(cfg IpcConfig, codec codec.Codec) (*ipcClient, error)

Create a new IPC client, UNIX domain socket on posix, named pipe on Windows

func StartIpc

func StartIpc(cfg IpcConfig, codec codec.Codec, apis ...api.EthereumApi) error

Start IPC server

Types

type EthereumClient

type EthereumClient interface {
	Close()
	Send(interface{}) error
	Recv() (interface{}, error)
}

type IpcConfig

type IpcConfig struct {
	Endpoint string
}

type PipeAddr

type PipeAddr string

PipeAddr represents the address of a named pipe.

func (PipeAddr) Network

func (a PipeAddr) Network() string

Network returns the address's network name, "pipe".

func (PipeAddr) String

func (a PipeAddr) String() string

String returns the address of the pipe

type PipeConn

type PipeConn struct {
	// contains filtered or unexported fields
}

PipeConn is the implementation of the net.Conn interface for named pipe connections.

func Dial

func Dial(address string) (*PipeConn, error)

Dial connects to a named pipe with the given address. If the specified pipe is not available, it will wait indefinitely for the pipe to become available.

The address must be of the form \\.\\pipe\<name> for local pipes and \\<computer>\pipe\<name> for remote pipes.

Dial will return a PipeError if you pass in a badly formatted pipe name.

Examples:

// local pipe
conn, err := Dial(`\\.\pipe\mypipename`)

// remote pipe
conn, err := Dial(`\\othercomp\pipe\mypipename`)

func DialTimeout

func DialTimeout(address string, timeout time.Duration) (*PipeConn, error)

DialTimeout acts like Dial, but will time out after the duration of timeout

func (*PipeConn) Close

func (c *PipeConn) Close() error

Close closes the connection.

func (*PipeConn) LocalAddr

func (c *PipeConn) LocalAddr() net.Addr

LocalAddr returns the local network address.

func (*PipeConn) Read

func (c *PipeConn) Read(b []byte) (int, error)

Read implements the net.Conn Read method.

func (*PipeConn) RemoteAddr

func (c *PipeConn) RemoteAddr() net.Addr

RemoteAddr returns the remote network address.

func (*PipeConn) SetDeadline

func (c *PipeConn) SetDeadline(t time.Time) error

SetDeadline implements the net.Conn SetDeadline method. Note that timeouts are only supported on Windows Vista/Server 2008 and above

func (*PipeConn) SetReadDeadline

func (c *PipeConn) SetReadDeadline(t time.Time) error

SetReadDeadline implements the net.Conn SetReadDeadline method. Note that timeouts are only supported on Windows Vista/Server 2008 and above

func (*PipeConn) SetWriteDeadline

func (c *PipeConn) SetWriteDeadline(t time.Time) error

SetWriteDeadline implements the net.Conn SetWriteDeadline method. Note that timeouts are only supported on Windows Vista/Server 2008 and above

func (*PipeConn) Write

func (c *PipeConn) Write(b []byte) (int, error)

Write implements the net.Conn Write method.

type PipeError

type PipeError struct {
	// contains filtered or unexported fields
}

PipeError is an error related to a call to a pipe

func (PipeError) Error

func (e PipeError) Error() string

Error implements the error interface

func (PipeError) Temporary

func (e PipeError) Temporary() bool

Temporary implements net.AddrError.Temporary()

func (PipeError) Timeout

func (e PipeError) Timeout() bool

Timeout implements net.AddrError.Timeout()

type PipeListener

type PipeListener struct {
	// contains filtered or unexported fields
}

PipeListener is a named pipe listener. Clients should typically use variables of type net.Listener instead of assuming named pipe.

func Listen

func Listen(address string) (*PipeListener, error)

Listen returns a new PipeListener that will listen on a pipe with the given address. The address must be of the form \\.\pipe\<name>

Listen will return a PipeError for an incorrectly formatted pipe name.

func (*PipeListener) Accept

func (l *PipeListener) Accept() (net.Conn, error)

Accept implements the Accept method in the net.Listener interface; it waits for the next call and returns a generic net.Conn.

func (*PipeListener) AcceptPipe

func (l *PipeListener) AcceptPipe() (*PipeConn, error)

AcceptPipe accepts the next incoming call and returns the new connection. It might return an error if a client connected and immediately cancelled the connection.

func (*PipeListener) Addr

func (l *PipeListener) Addr() net.Addr

Addr returns the listener's network address, a PipeAddr.

func (*PipeListener) Close

func (l *PipeListener) Close() error

Close stops listening on the address. Already Accepted connections are not closed.
