A Conn represents a 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.
func NewConn(c net.Conn) (*Conn, error)

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. Data returns the data field of the control message at the head on
m. Marshal marshals the control message at the head on m, and returns
the next control message. MarshalHeader marshals the header fields of the control message at
the head on m. Next returns the control message at the next on m.
Next works only for standard control messages. Parse parses m as a single or multiple control messages.
Parse works for both standard and compatible messages. ParseHeader parses and returns the header fields of the control
message at the head on m.
func NewControlMessage(dataLen []int) ControlMessage
func ControlMessage.Marshal(lvl, typ int, data []byte) (ControlMessage, error)
func ControlMessage.Next(dataLen int) ControlMessage
func ControlMessage.Parse() ([]ControlMessage, error)
A Message represents an IO message. 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. 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. // protocol-specific information on the received message // # of bytes read or written from/to Buffers // # of bytes read or written from/to OOB OOB contains protocol-specific control or miscellaneous
ancillary data known as out-of-band data.
func (*Conn).RecvMsg(m *Message, flags int) error
func (*Conn).RecvMsgs(ms []Message, flags int) (int, error)
func (*Conn).SendMsg(m *Message, flags int) error
func (*Conn).SendMsgs(ms []Message, flags int) (int, error)
An Option represents a sticky socket option. // length of value in bytes; must be equal or greater than 1 // level // name; must be equal or greater than 1 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.
