====
+ares_reinit()
+
+- To allow an app to force a re-read of /etc/resolv.conf etc, pretty much
+ like the res_init() resolver function offers
+
ares_gethostbyname
- When built to support IPv6, it needs to also support PF_UNSPEC or similar,
so that an application can ask for any protocol and then c-ares would return
all known resolves and not just explicitly IPv4 _or_ IPv6 resolves.
+
+ares_process
+
+- Upon next ABI breakage ares_process() should be changed to return 'int'
+ and return ARES_ENOTINITIALIZED if ares_library_init() has not been called.
+
+ares_process_fd
+
+- Upon next ABI breakage ares_process_fd() should be changed to return
+ 'int' and return ARES_ENOTINITIALIZED if library has not been initialized.
