/******************************************************************
Revision history:
1998/04/28 (Sean Reifschneider)
- When facility not specified to syslog() method, use default from openlog()
(This is how it was claimed to work in the documentation)
- Potential resource leak of o_ident, now cleaned up in closelog()
- Minor comment accuracy fix.
95/06/29 (Steve Clift)
- Changed arg parsing to use PyArg_ParseTuple.
- Added PyErr_Clear() call(s) where needed.
- Fix core dumps if user message contains format specifiers.
- Change openlog arg defaults to match normal syslog behavior.
- Plug memory leak in openlog().
- Fix setlogmask() to return previous mask value.
