Hi!
I'm developing a daemon that will:
- start/stop
- send signals
- check status
of some services.
This can be done via s6-svc or s6-svstat but:
1. Can I use the underlying calls from libs6?
2. Is this interface likely to change?
If you mean send commands to s6-supervise via s6_svc_writectl(),
and read the status file via s6_svstatus_read(), then yes, you can use
those calls, and no, it's probably not going to change.
The contents of a s6_svstatus_t structure, however, may be expanded in
the future. I think you can rely on backwards compatibility, i.e. all
the current fields will remain there with the same meaning; but do not
assume that they are no other fields.
