source: libcaca/trunk/test/event.c @ 1256

Last change on this file since 1256 was 1256, checked in by Sam Hocevar, 14 years ago
  • Remove cucul_set_color() from the exported API and replaced all calls with cucul_set_attr_ansi(). Old application will still compile (but issue a warning) and run, though.
  • Property svn:keywords set to Id
