Revision history for libev, a high-performance and full-featured event loop.
TODO: include ev_xyz_start in each example?
TODO: ev_pdef stupid idea?
TODO: EVRUN_XXX?
- "PORTING FROM LIBEV 3.X TO 4.X" (in ev.pod) is recommended reading.
- ev_embed_stop did not correctly stop the watcher (very good
testcase by Vladimir Timofeev).
@ -46,8 +48,6 @@ TODO: include ev_xyz_start in each example?
- improve compatibility to older C++ compilers.
- (experimental) ev_run/ev_default_loop/ev_break/ev_loop_new have now
default arguments when compiled as C++.
- (experimental) all ev_functions that accept only a loop argument
default that to EV_DEFAULT_UC when compiled as C++.
3.9 Thu Dec 31 07:59:59 CET 2009
- signalfd is no longer used by default and has to be requested
