Type-specialised unpack.

type Blob = ByteString

Type for Word8 arrays, these are stored with an Datum length prefix.

blob_pack :: [Word8] -> Blob

Type-specialised pack.

type Time = Double

A real-valued time stamp. For Osc proper this is an Ntp64 time in real-valued (fractional) form. For SuperCollider Nrt programs this is elapsed time since the start of the score. This is the primary form of timestamp used by hosc.

data Datum

The basic elements of Osc messages.
