source: libcaca/trunk/src/time.c @ 331

Last change on this file since 331 was 331, checked in by Sam Hocevar, 17 years ago
  • test/event.c: + Do not refresh after each event, but only when there is no event

pending.

+ If the pressed key is a printable character, display it.

  • src/time.c: + Moved _caca_getticks() to this file.
  • src/caca.c: + Set the escape delay to a very low value in the ncurses driver,

because I don't want escape sequences to be entered manually.

  • src/io.c: + Autorepeat emulation in the ncurses and slang drivers: do not

immediately send the key release event.

  • configure.ac: + Check for usleep. + Improvements in the win32 platform detection.
  • Property svn:keywords set to Id
