diff src/event/ngx_event_udp.h @ 8810:2dfd313f22f2 quic
Core: made the ngx_sendmsg() function non-static.
Additionally, the ngx_init_srcaddr_cmsg() function is introduced which
initializes control message with connection local address.
The NGX_HAVE_ADDRINFO_CMSG macro is defined when at least one of methods
to deal with corresponding control message is available.
