352  * @return Generic Netlink family object or NULL if no match was found.
372  * Search controller cache for a family name match
374  * @arg name		Name of Generic Netlink family
377  * that matches the specified family \c name. If a match is found successfully,

417  * Resolve Generic Netlink family name to numeric identifier
419  * @arg name		Name of Generic Netlink family
421  * Resolves the Generic Netlink family name to the corresponding numeric
422  * family identifier. This function queries the kernel directly, use
427  * @return The numeric family identifier or a negative error code.
