Unused parameters in lib files

[dengeltheyounger]

I've noticed that in the lib folder that are at least a few files that take a socklen_t parameter. Notable examples of this are sock_cmp_addr, sock_cmp_port, and sock_get_port (although, there are others).

None of these functions actually use the socklen_t parameter. Moreover, the sockaddr_in and sockaddr_in6 structs have their on sa_len member. Any idea why the author required the socklen_t parameter despite not actually using it?
