7 logger.c is part of the utils section in the libatalk library,
8 which is part of the netatalk project.
10 logger.c was written by Simon Bazley (sibaz@sibaz.com)
12 I believe libatalk is released under the L/GPL licence.
14 Just incase, it is, thats the licence I'm applying to this file.
18 ==========================================================================
20 Logger.c is intended as an alternative to syslog for logging
22 ---------------------------------------------------------------
24 The initial plan is to create a structure for general information needed
27 Initally I'll hard code the neccesary stuff to start a log, this should
28 probably be moved elsewhere when some code is written to read the log
29 file locations from the config files.
31 As a more longterm idea, I'll code this so that the data struct can be
32 duplicated to allow multiple concurrent log files, although this is
33 probably a recipe for wasted resources.
