+
+ * log.c: (vzlog) Take a single va_list argument and use va_copy
+ as necessary for multiple traversals.
+ (zlog) Pass only one va_list to vzlog.
+ (zlog_*,plog_*) Use a macro for boilerplate code; pass only one
+ va_list to vzlog.
+ (zlog_set_file) Remove unused 2nd argument (flags).
+ (zlog_save_cwd,zlog_get_cwd,zlog_free_cwd) Remove unused functions.
+ * log.h: Remove ZLOG_*_INDEX defines (no longer used).
+ Remove unused 2nd argument from zlog_set_file prototype.
+ Fix prototype for zlog_rotate.
+ * command.c: (config_log_file) Remove unused 2nd arg to zlog_set_file.
+ * vty.c: (vty_out) Fix stdarg usage to perform multiple traversals
+ properly.
+ (vty_log) Must use va_copy for multiple traversals of va_list arg.
+
2004-11-19 David Young <dyoung@pobox.com>
* log.c: (safe_strerror) New function: safe wrapper for strerror.
