Subject: MINOR: stconn: add sc_hastream() and __sc_hastream() helpers
X-Git-Url: http://www.kaiwu.me/postgresql/commit/static/gitweb.js?a=commitdiff_plain;h=e08b126fbbb267c508900d8ac130d4d76f15ef3c;p=haproxy.git

MINOR: stconn: add sc_hastream() and __sc_hastream() helpers

This patch introduces the sc_hastream() and __sc_hastream() inline
helpers to retrieve a haload stream context (struct hastream) from
a stream connector.

These functions allow the stconn layer to safely access haload-specific
stream data when the application type is OBJ_TYPE_HXLOAD.
