DESCRIPTION
     These functions provide a means of querying OpenRC services to find out
     the state of each one, to start and stop it, and any other functions
     related to it.

     Most functions should be self descriptive as to what they do and what
     they return based on names and arguments.

     rc_service_add() adds the service to the runlevel.

     rc_service_delete() deletes the service from the runlevel.

     rc_service_daemon_set() saves the arguments in the service state data so
     that rc_service_daemons_crashed() can check to see if they are still run‐
     ning or not.

     rc_service_description() returns the description variable of the service.
     If option is not null then we return the description_$option variable
     instead.

     rc_service_exists() returns true if the service exists, otherwise false.

     rc_service_in_runlevel() returns true if the service is in the runlevel,
     otherwise false.

     rc_service_mark() puts the service into the given state.  If the state is
     RC_SERVICE_STOPPED then all data associated with the service is lost.
     rc_service_extra_commands() returns a list of extra commands the service
     supports beyond the default ones. See runscript for default commands.

     rc_service_plugable() returns true if the service is allowed to be
     plugged by rc.conf.  Default is true.

     rc_service_resolve() resolves service to the full path of service that
     was started, or would be started.

     When service starts, it starts service_to_start afterswards as directed
     by rc_service_schedule_start().  rc_services_scheduled() returns a list
     of services that will be started when service starts.
     rc_service_schedule_clear() clears these scheduled services for service.

     rc_service_state(returns, the, state, of) service.	 The return value is a
     bitmask, where more than one state can apply.

     rc_service_started_daemon() checks to see if service started exec using
     start-stop-daemon.	 If indx is greater than zero, then it must also be
     the nth daemon started by service.	 rc_service_value_set() saves the
     value under the name option.  rc_service_value_get() returns the value of
     the saved option.

     rc_services_in_runlevel() returns a list of services in runlevel.	If
     runlevel is not specified, then it returns a list of all available ser‐
     vices.

     rc_services_in_state() returns a list of all the services in state.

IMPLEMENTATION NOTES
     Each function that returns char * returns a malloced NULL terminated
     string that should be freed when done.

     Each function that returns RC_STRINGLIST * should be freed using
     rc_stringlist_free() when done.

     When a function fails it should either return false or NULL and set errno
     unless specified otherwise as above.

FILES
     /lib/rc/init.d normally holds the volatile state data for services on a
     RAM backed disk.

     errno(3), malloc(3), free(3) rc_stringlist_free(3), start-stop-daemon(8)
