Functions

func Decode

func Decode(d, in []byte) (n int, e error)

Decode decodes a TCOBS frame `in` (without 0-delimiter) to `d` and returns as `n` the valid data length from the end in `d`. ATTENTION: d is filled from the end! decoded := d[len(d)-n:] is the final result. In case of an error n is 0. n can be 0 without having an error. Framing with 0-delimiter to be done before is assumed, so no 0-checks performed. For details see TCOBSSpecification.md.
