Exported Values


	  var AcceptFunc (int) (int, syscall.Sockaddr, error)
		AcceptFunc is used to hook the accept call.


	  var CloseFunc (int) error
		CloseFunc is used to hook the close call.


	 func DupCloseOnExec(fd int) (int, string, error)
		DupCloseOnExec dups fd and marks it close-on-exec.


	  var ErrDeadlineExceeded error
		ErrDeadlineExceeded is returned for an expired deadline.
		This is exported by the os package as os.ErrDeadlineExceeded.


	  var ErrFileClosing error
		ErrFileClosing is returned when a file descriptor is used after it
		has been closed.


	  var ErrNetClosing error
		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 ErrNoDeadline error
		ErrNoDeadline is returned when a request is made to set a deadline
		on a file type that does not use the poller.


	  var ErrNotPollable error
		ErrNotPollable is returned when the file or socket is not suitable
		for event notification.


	 func IsPollDescriptor(fd uintptr) bool
		IsPollDescriptor reports whether fd is the descriptor being used by the poller.
		This is only used for testing.


	  var TestHookDidWritev func(wrote int)
		TestHookDidWritev is a hook for testing writev.
