Something like this is available in "org.freesmartphone.Time.Alarm" interface of otimed. Each app can only register one timestamp. When the Alarm time is reached the service will call org.freesmartphone.Application.Alarm() on the sender. This is not yet documented, please look at subsystems/otimed/alarm.py for more details. :( -- Jan Lübbe <jlue...@lasnet.de> http://sicherheitsschwankung.de gpg-key 1024D/D8480F2E 2002-03-20 fingerprint 1B25 F91F 9E7B 5D4F 1282 02D6 8A83 8BE4 D848 0F2E _______________________________________________ smartphones-standards mailing list smartphones-standards@linuxtogo.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/smartphones-standards
