Subject svn commit: r123950 - /apr/apr/trunk/include/apr_network_io.h /apr/apr/trunk/network_io/unix/multicast.c
Date Mon, 03 Jan 2005 07:37:36 GMT

New Revision: 123950

URL: http://svn.apache.org/viewcvs?view=rev&rev=123950
Log:
Add arguments for Single Source Multicast Support as suggested by Colm 
MacCarthaigh on dev@apr.

SSM Support is not implemented, but I added it in the interest of making
a single API that can be used in the future.
