liblo is an implementation of the Open Sound Control[1] protocol for POSIX systems. It is written in ANSI C and released under the GNU General Public Licence. It is designed to make developing OSC applictions as easy as possible. http://plugin.org.uk/liblo/ This release adds some OSX compatibility fixes from Taybin Rutkin, support for OSC multipath pattern matching courtesy of Daniel Holth's pattern matcher and I've added bundle i/o. Liblo now implements everything in the OSC specification except type arrays. Pattern matching and bundles are largly untested, and should be treated as alpha quality, but should work. If you are using server threads or the nonblock API then bundles should JustWork(TM), if you are polling on the server fd then you have some work to do. There are API calls for detecting if/when there are scheduled messages. - Steve [1] http://www.cnmat.berkeley.edu/OpenSoundControl/
