|
) |
| | |
Adds a callback to invoke when an event occurred on a descriptor.
- Parameters:
-
| fd | the descriptor |
| callback | the callback to invoke |
| user | user data to pass to the callback |
void base::STEventDaemon::delCallback |
( |
int |
fd |
) |
|
Removes a callback.
- Parameters:
-
| fd | the descriptor to remove the callback for |
bool base::STEventDaemon::dumpState |
( |
bool |
force |
) |
[protected, virtual] |
Dumps the daemon state into the log file.
The daemon state contains information on its internal state
- Parameters:
-
| force | force dump, otherwise it is only dumped if the last dump was more than one minute ago |
- Returns:
- true if the state has been dumped, false if not
Reimplemented from base::Daemon.
virtual int base::STEventDaemon::loop |
( |
|
) |
[protected, virtual] |
The main loop.
- Returns:
- the daemon's exit code
