11.15 srfi-66 - Octet vectors

Module: srfi-66

This module defines procedures to deal with u8vectors; they are almost a subset of srfi-4 and gauche.uvector (see Uniform vectors, except one procedure, u8vector-copy!, which has different argument orders (unfortunate historical artifacts).

The following procedures are the same as gauche.uvector:

u8vector?       make-u8vector      u8vector
u8vector->list  list->u8vector
u8vector-length u8vector-ref       u8vector-set!
u8vector=?      u8vector-compare   u8vector-copy
Function: u8vector-copy! src sstart target tstart n

[SRFI-66] {srfi-66} Copy the content of an u8vector src, starting from sstart for n octets, into an u8vector target beginning from tstart. The target u8vector must be mutable.

Note that gauche.uvector has also u8vector-copy!, but its argument order is as follows, where send is (+ sstart n):

(u8vector-copy! target tstart src sstart send)

Gauche’s argument order is consistent with vector-copy! of R7RS, srfi-43 and srfi-133.

We recommend to use srfi-66 only for porting third-party libraries to avoid confusion.
