.Sh DESCRIPTION
The
.Nm lib80211
library is an interface to the
.Xr net80211 4
infrastructure.
It implements wrappers around the
.Xr net80211 4
ioctl command, as well as providing a convenient API to access the regulatory
database.
.Pp
The
.Fn lib80211_alloc_regdata
and
.Fn lib80211_free_regdata
function allocates / frees a regdata structure to store regulatory domain
information in.
.Pp
The
.Fn lib80211_regdomain_readconfig
and
.Fn lib80211_regdomain_cleanup
functions read in the regulatory database XML configuration and free it when
finished.
.Pp
The
.Fn lib80211_regdomain_findbysku
and
.Fn lib80211_regdomain_findbyname
functions lookup a regulatory domain entry by SKU enum and SKU name
respectively.
.Pp
The
.Fn lib80211_country_findbycc
and
.Fn lib80211_country_findbyname
functions lookup a country information entry by ISO country enum and
ISO country code string respectively.
