DESCRIPTION

The lib80211 library is an interface to the net80211(4) infrastructure. It implements wrappers around the net80211(4) ioctl command, as well as providing a convenient API to access the regulatory database.

The lib80211_alloc_regdata() and lib80211_free_regdata() function allocates / frees a regdata structure to store regulatory domain information in.

The lib80211_regdomain_readconfig() and lib80211_regdomain_cleanup() functions read in the regulatory database XML configuration and free it when finished.

The lib80211_regdomain_findbysku() and lib80211_regdomain_findbyname() functions look up a regulatory domain entry by SKU enum and SKU name respectively.

The lib80211_country_findbycc() and lib80211_country_findbyname() functions look up a country information entry by ISO country enum and ISO country code string respectively.

RETURN VALUES

The lib80211_alloc_regdata(), lib80211_regdomain_readconfig(), lib80211_regdomain_findbysku(), lib80211_regdomain_findbyname(), lib80211_country_findbycc(), lib80211_country_findbyname() return NULL upon error.

HISTORY

The lib80211 library first appeared in FreeBSD 11.0.
