source: trunk/abcl/src/org/armedbear/lisp/socket.lisp @ 13072

Last change on this file since 13072 was 13072, checked in by Mark Evenson, 11 years ago

Sockets can be created with :element-type equivalent to (UNSIGNED-BYTE 8).

Fixes error reported by Cyrus Harmon where passing an :ELEMENT-TYPE of
FLEXI-STREAMS:OCTET to the GET-SOCKET-STREAM call would fail.
