ErrFileClosing is returned when a file descriptor is used after it has been closed.
var ErrFileClosing = errors.New("use of closed file")
ErrNetClosing is returned when a network descriptor is used after it has been closed. Keep this string consistent because of issue #4373: since historically programs have not been able to detect this error, they look for the string.
var ErrNetClosing = errors.New("use of closed network connection")
ErrNoDeadline is returned when a request is made to set a deadline on a file type that does not use the poller.
var ErrNoDeadline = errors.New("file type does not support deadline")
ErrTimeout is returned for an expired deadline.
var ErrTimeout error = &TimeoutError{}
TestHookDidWritev is a hook for testing writev.
var TestHookDidWritev = func(wrote int) {}
func PollDescriptor() uintptr
PollDescriptor returns the descriptor being used by the poller, or ^uintptr(0) if there isn't one. This is only used for testing.
func SendFile(dstFD *FD, src int, remain int64) (int64, error)
SendFile wraps the sendfile system call.
FD is a file descriptor. The net and os packages use this type as a field of a larger type representing a network connection or OS file.
type FD struct {
// System file descriptor. Immutable until Close.
Sysfd int
// Whether this is a streaming descriptor, as opposed to a
// packet-based descriptor like a UDP socket. Immutable.
IsStream bool
// Whether a zero byte read indicates EOF. This is false for a
// message based socket connection.
ZeroReadIsEOF bool
// contains filtered or unexported fields
}
func (fd *FD) Accept() (int, syscall.Sockaddr, string, error)
Accept wraps the accept network call.
func (fd *FD) Close() error

Ftruncate wraps syscall.Ftruncate.
func (fd *FD) Init(net string, pollable bool) error
Init initializes the FD. The Sysfd field should already be set. This can be called multiple times on a single FD. The net argument is a network name from the net package (e.g., "tcp"), or "file". Set pollable to true if fd should be managed by runtime netpoll.
func (fd *FD) Pread(p []byte, off int64) (int, error)
Pread wraps the pread system call.
func (fd *FD) Pwrite(p []byte, off int64) (int, error)

func (fd *FD) RawControl(f func(uintptr)) error
RawControl invokes the user-defined function f for a non-IO operation.
func (fd *FD) RawRead(f func(uintptr) bool) error
RawRead invokes the user-defined function f for a read operation.
func (fd *FD) RawWrite(f func(uintptr) bool) error
RawWrite invokes the user-defined function f for a write operation.
func (fd *FD) Read(p []byte) (int, error)
Read implements io.Reader.
func (fd *FD) ReadDirent(buf []byte) (int, error)
