Function Documentation
◆ signalHandlerMask()
| sigset_t* signalHandlerMask | ( | void | ) |
Return a signal mask with suitable defaults.
Allocates and returns as signal mask that blocks all of the signals that we have explicit handlers for.
This can then be used to ensure that source handling threads do not respond to signals, and that the main logging thread doesn't respond to any of these signals until it's ready to do so.
The signal set returned by this function must be freed by the caller.
- Returns
- Pointer to sigset_t
If any new signal handlers are added, they also need to be added to this list

◆ signalHandlersInstall()
| void signalHandlersInstall | ( | void | ) |
Install signal handlers.
Called from main logging thread to establish the signal handlers.
