+
+ * Added SILC Dir API to lib/silcutil/silcdir.h. Implemented it
+ for Unix (POSIX). Affected files are lib/silcutil/silcdir.h,
+ lib/silcutil/unix/silcunixdir.c.
+
Sun Jan 13 17:11:26 EET 2008 Pekka Riikonen <priikone@silcnet.org>
* Added silc_buffer_memcmp and silc_buffer_tail. Fixed SilcBuffer
o Fix universal time decoding (doesn't accept all formats) in silctime.c.
- o Add directory opening/traversing functions
-
- o regex from /lib/contrib to lib/silcutil, define SILC Regex API. (***DONE)
-
o Additional scheduler changes: optimize silc_schedule_wakeup. Wakeup
only if the scheduler is actually waiting something. If it is
delivering tasks wakeup is not needed.
SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
in separately.
+ o Add directory opening/traversing functions (***DONE, TODO Windows & Symbian)
+
+ o regex from /lib/contrib to lib/silcutil, define SILC Regex API. (***DONE)
+
o Add functions to manipulate environment variables. (***DONE)
o Add functions to loading shared/dynamic object symbols (replaces the
