Deucе authoredThe first entry I tried adding was "Example..." which was not a valid hostname, but was copied into the address and looked silly. Now only copies into address if it's a valid, usable hostname. Also, add a convenience macro to check if a connection type uses the network or not. New functions in netwrap: bool isValidHostname(const char *str); bool isValidAddressString(const char *str); bool isResolvableHostname(const char *str); We ust the last one (which calls the other two) for this feature now.
