OW_CIMOMSERVER_API void OW_NAMESPACE::Platform::rerunDaemon (   ) 
 

Re-run the daemon.

This closes all file handles and then calls execv to replace the current process with a new copy of the daemon. precondition: daemonInit() must have been called previously, because the same set of arguments will be passed to execv().

This function does not return.

Exceptions:
DaemonException in the case execv() fails.

OW_CIMOMSERVER_API void OW_NAMESPACE::Platform::restartDaemon (   ) 
 

Restart the daemon.

This initiates the restart process. On POSIX platforms, it just sends a SIGHUP to the main process.
