Please don't call the function "writev" so that nobody associates it with the guarantees that only POSIX provides, but none of the emulations. Call it "write_gather", for example.

Also, clearly document that its only purpose is to reduce sequences of write() calls to a single function call, but that the additional writev guarantees are not needed.

A range-diff to the earlier round would have been very helpful.
