.PP
If
\fIsrc\fR
and
\fIdst\fR
are single bios, bi_next must be NULL \- otherwise, treats
\fIsrc\fR
and
\fIdst\fR
as linked lists of bios\&.
.PP
Stops when it reaches the end of either
\fIsrc\fR
or
\fIdst\fR
\- that is, copies min(src\->bi_size, dst\->bi_size) bytes (or the equivalent for lists of bios)\&.
