Subject: MINOR: raw_sock: Add a close method.
X-Git-Tag: v2.4-dev13~8
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ca1a57f022900f60d2f483c13df9ff29e5145e7d;p=thirdparty%2Fhaproxy.git

MINOR: raw_sock: Add a close method.

Add a close() method, that explicitely cancels any subscription on the
connection, in preparation for future evolutions.
