.Sh NAME
.Nm rc_runlevel_get , rc_runlevel_exists , rc_runlevel_list , rc_runlevel_set ,
.Nm rc_runlevel_starting , rc_runlevel_stopping
.Nd RC runlevel functions
.Sh LIBRARY
Run Command library (librc, -lrc)
.Sh SYNOPSIS
.In rc.h
.Ft "char *" Fn rc_runlevel_get void
.Ft bool Fn rc_runlevel_exists
.Ft "RC_STRINGLIST *" Fn rc_runlevel_list void
.Ft bool Fn rc_runlevel_set "const char *runlevel"
.Ft bool Fn rc_runlevel_starting void
.Ft bool Fn rc_runlevel_stopping void
.Sh DESCRIPTION
These functions provide a means of querying OpenRC to find out which runlevel
we are in and what services are in which runlevel.
.Sh IMPLEMENTATION NOTES
Each function that returns
.Fr "char *"
returns a malloced NULL terminated string that should be freed when done.
.Pp
Each function that returns
.Fr "RC_STRINGLIST *"
should by freed by calling
.Fn rc_stringlist_free
when done.
.Sh FILES
.Pa /etc/init.d/functions.sh
is provided by OpenRC, which allows shell scripts to use the above functions.
For historical reasons our verbose functions are prefixed with v instead of
suffixed. So einfov becomes veinfo, einfovn becomes veinfon.
Rinse and repeat for the other verbose functions.
