- /******************************************************************
- 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.
