NativeEndian is the machine native endian implementation of ByteOrder.
ControlMessageSpace returns the whole length of control message.
type Conn struct {
// contains filtered or unexported fields
}A Conn represents a raw connection.
NewConn returns a new raw connection.
RecvMsg wraps recvmsg system call.
The provided flags is a set of platform-dependent flags, such as syscall.MSG_PEEK.
RecvMsgs wraps recvmmsg system call.
It returns the number of processed messages.
The provided flags is a set of platform-dependent flags, such as syscall.MSG_PEEK.
Only Linux supports this.
SendMsg wraps sendmsg system call.
The provided flags is a set of platform-dependent flags, such as syscall.MSG_DONTROUTE.
SendMsgs wraps sendmmsg system call.
It returns the number of processed messages.
The provided flags is a set of platform-dependent flags, such as syscall.MSG_DONTROUTE.
Only Linux supports this.
A ControlMessage represents the head message in a stream of control messages.
A control message comprises of a header, data and a few padding fields to conform to the interface to the kernel.
See RFC 3542 for further information.
func NewControlMessage(dataLen []int) ControlMessage
NewControlMessage returns a new stream of control messages.
func (m ControlMessage) Data(dataLen int) []byte
Data returns the data field of the control message at the head on m.
func (m ControlMessage) Marshal(lvl, typ int, data []byte) (ControlMessage, error)
Marshal marshals the control message at the head on m, and returns the next control message.
func (m ControlMessage) MarshalHeader(lvl, typ, dataLen int) error
MarshalHeader marshals the header fields of the control message at the head on m.
func (m ControlMessage) Next(dataLen int) ControlMessage
Next returns the control message at the next on m.
Next works only for standard control messages.
func (m ControlMessage) Parse() ([]ControlMessage, error)
Parse parses m as a single or multiple control messages.
Parse works for both standard and compatible messages.
func (m ControlMessage) ParseHeader() (lvl, typ, dataLen int, err error)
ParseHeader parses and returns the header fields of the control message at the head on m.
type Message struct {
// When writing, the Buffers field must contain at least one
// byte to write.
// When reading, the Buffers field will always contain a byte
// to read.
Buffers [][]byte
// OOB contains protocol-specific control or miscellaneous
// ancillary data known as out-of-band data.
OOB []byte
// Addr specifies a destination address when writing.
// It can be nil when the underlying protocol of the raw
// connection uses connection-oriented communication.
// After a successful read, it may contain the source address
// on the received packet.
Addr net.Addr
N int // # of bytes read or written from/to Buffers
NN int // # of bytes read or written from/to OOB
Flags int // protocol-specific information on the received message
}A Message represents an IO message.
type Option struct {
Level int // level
Name int // name; must be equal or greater than 1
Len int // length of value in bytes; must be equal or greater than 1
}An Option represents a sticky socket option.
Get reads a value for the option from the kernel. It returns the number of bytes written into b.
GetInt returns an integer value for the option.
The Len field of Option must be either 1 or 4.
Set writes the option and value to the kernel.
SetInt writes the option and value to the kernel.
The Len field of Option must be either 1 or 4.
