From: Donn Terry <donn@hpfcrn.fc.hp.com> (More to "is struct utimbuf...") Don Lewine's posting reminded me (I can't remember EVERYTHING) about the issue of additional fields in structures. All my comments in my previous posting stand, but apply primarily to structures that are filled in (at least initially) by the system. For ones that are sent to the system, created from "nowhere", there is an additional problem, that of "how can a portable application know to/how to initialize additional (vendor-defined) fields?". The solution in the 1990 revision is to prohibit additional fields for the structures like that. (A vendor is then required to provide a new call to set microseconds, or whatever.) It was agreed that this was not the most desireable solution, but it was the only one that worked. Donn Terry Same disclaimer. Volume-Number: Volume 21, Number 6
