However, the document does have a definition of contradictory flags (Section 2) and explicitly describes what the API must do when getting them (Section 6) i.e., causes error EINVAL. Or EAI_BADEXTFLAGS for getaddrinfo (Section 7). I do agree though that there's something wrong in the text in Section 10 about application requirements. Perhaps s/MUST not/should not/. This may apply to some other text in Section 10, too. Jari _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
