2001-02-20 Werner Koch <wk@gnupg.org>
* w32-io.c (destroy_reader,kill_reader): New.
(create_reader, reader): Add a new event to stop the thread.
(_gpgme_io_close): Kill the reader thread.
* posix-io.c (_gpgme_io_select): Handle frozen fds here.
* 32-io.c (_gpgme_io_select): Ditto. Removed a bunch of unused code.
* wait.c: Reworked the whole thing.
* rungpg.c (_gpgme_gpg_new): Init pid to -1.
(_gpgme_gpg_release): Remove the process from the wait queue.
2001-02-19 Werner Koch <wk@gnupg.org>
* w32-io.c (_gpgme_io_set_close_notify): New.
(_gpgme_io_close): Do the notification.
* posix-io.c (_gpgme_io_select): Use a 1 sec timeout and not 200
microseconds.
