getaddrinfo was designed to be extensible as was struct addrinfo. Part of the problem with TTL is not data sources used by getaddrinfo have TTL information. Additionally for many uses you want to reconnect to the same server rather than the same name. Note there is nothing to prevent a getaddrinfo implementation maintaining its own cache though if I was implementing such a cache I would have a flag to to force a refresh.
Sorry if I wasn't clear... My point to Bill was that we should be using calls that don't have TTL information (GAI/GNI in their default forms). That we don't need to abuse connect() to achieve that. That if people use GAI/GNI(), then, any brokenness is system-wide brokenness in the system's resolver library and should be addressed there. Owen
