'closelog' closes the current Syslog connection, if there is one. This includes closing the '/dev/log' socket, if it is open. 'closelog' also sets the identification string for Syslog messages back to the default, if 'openlog' was called with a non-NULL argument to IDENT. The default identification string is the program name taken from argv[0]. If you are writing shared library code that uses 'openlog' to generate custom syslog output, you should use 'closelog' to drop the GNU C Library's internal reference to the IDENT pointer when you are done. Please read the section on 'openlog' for more information: *Note openlog::. 'closelog' does not flush any buffers. You do not have to call 'closelog' before re-opening a Syslog connection with 'openlog'. Syslog connections are automatically closed on exec or exit.
