For this in particular, there is pointer->bytevector, bytevector->pointer and bytevector-TYPE-ref, bytevector-TYPE-set! (it’s not limited to only bytes, also floats are available IIRC).
Don’t do bytevector->pointer + pointer->bytevector + … in long sequences though, or else this loop will use memory proportional to the length to this sequence. (This is intentionally undocumented (*).)
Best regards,
Maxime Devos
