Types

type Conn

type Conn interface {
	// SyscallConn returns a raw network connection.
	SyscallConn() (RawConn, error)
}

Conn is implemented by some types in the net and os packages to provide access to the underlying file descriptor or handle.

type Errno

type Errno uintptr

An Errno is an unsigned number describing an error condition. It implements the error interface. The zero Errno is by convention a non-error, so code to convert from Errno to error should use:

err = nil
if errno != 0 {
        err = errno
}

func (Errno) Error

func (e Errno) Error() string

func (Errno) Is

func (e Errno) Is(target error) bool

func (Errno) Temporary

func (e Errno) Temporary() bool

func (Errno) Timeout

func (e Errno) Timeout() bool

type RawConn

type RawConn interface {
	// Control invokes f on the underlying connection's file
	// descriptor or handle.
	// The file descriptor fd is guaranteed to remain valid while
	// f executes but not after f returns.
	Control(f func(fd uintptr)) error

	// Read invokes f on the underlying connection's file
	// descriptor or handle; f is expected to try to read from the
	// file descriptor.
	// If f returns true, Read returns. Otherwise Read blocks
	// waiting for the connection to be ready for reading and
	// tries again repeatedly.
	// The file descriptor is guaranteed to remain valid while f
	// executes but not after f returns.
	Read(f func(fd uintptr) (done bool)) error

	// Write is like Read but for writing.
	Write(f func(fd uintptr) (done bool)) error
}

A RawConn is a raw network connection.

type Rlimit

type Rlimit struct {
	Cur uint64
	Max uint64
}

type SockaddrInet4

type SockaddrInet4 struct {
	Port int
	Addr [4]byte
	// contains filtered or unexported fields
}

type SockaddrInet6

type SockaddrInet6 struct {
	Port   int
	ZoneId uint32
	Addr   [16]byte
	// contains filtered or unexported fields
}
