Programmatically adding an element into a map using libnftnl

[Kiernan George <kbg98@xxxxxx>]

I have a map of the following format:

{ type ipv4_addr . inet_service : ipv4_addr }

How do I add an element into the map using the libnftnl API? I see the
example nft-set-elem-add.c, but it is not clear on how to modify this
for different types of elements like concatenated IP/port above or
IPV6.

I hate to ask again, but is there documentation for the library somewhere?
