Types

type Buffer

type Buffer struct {
	Data []byte

	ReaderPos *uint32
	WriterPos *uint32
}

Buffer provides a memory-layout agnostic and safe interface for writing to or reading from a shared Xen ring buffer.

func (*Buffer) Read

func (buf *Buffer) Read(data []byte) (int, error)

Read reads bytes from buf into data, updates the position, and returns the number of bytes read.

func (*Buffer) Write

func (buf *Buffer) Write(data []byte) (int, error)

Write writes bytes from data info buf, updates the position, and returns the number of bytes written.
