Subject: Simplified ngx_unix_recv() and ngx_readv_chain().
X-Git-Tag: release-1.9.15~13
X-Git-Url: http://www.kaiwu.me/postgresql/commit/static/gitweb.js?a=commitdiff_plain;h=4d1f67fd910a183ded8b4399f81c20c2a67ac83e;p=nginx.git

Simplified ngx_unix_recv() and ngx_readv_chain().

This makes ngx_unix_recv() and ngx_udp_unix_recv() differ minimally.
