Functions

func EnsureBufBigEnough

func EnsureBufBigEnough(buf []byte, needed int) []byte

EnsureBufBigEnough checks that given buffer is big enough to hold 'needed' bytes, otherwise returns a buffer of a size of at least 'needed' bytes.

func ReadInt

func ReadInt(r io.Reader) (int, error)

ReadInt reads an int (4 bytes) from the reader using ByteOrder.

func WriteInt

func WriteInt(w io.Writer, v int) error

WriteInt writes an int (4 bytes) to the given writer using ByteOrder.
