this is wrong. sizeof(out_name) is the size of the pointer, but not the
size of the storage behind it. To be able to use strscpy() here you
need to pass in the size of the given buffer and use that.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea. [ RFC1925, 2.3 ]
