Subject: io: allow freeing of io_conn at any time.
X-Git-Url: https://git.ozlabs.org/?a=commitdiff_plain;h=31c816a6a9a2037d8860d56814835d9ac488d52f;hp=31c816a6a9a2037d8860d56814835d9ac488d52f;p=ccan

io: allow freeing of io_conn at any time.

io_close() currently marks the io_conn for freeing, but doesn't
actually do it.  This is a problem for tal() users, because we can't
just call it in the parent's constructor.

Make io_close() just tal_free() + return &io_conn_freed (a magic
io_plan pointer).
