Should writev(2) be avoided?

[Svante Lindahl]

Is there a good reason to avoid the system call writev(2)?
The reason I ask is, I've never seen it in any code, but I
think it would be useful for something I'm writing now.

If writev is BSD only (is it?), that's not a big problem, it
can be emulated well enough for my needs should the code need
to be moved to a non-BSD derived environment. Will writev be
in SysVr4? If it wouln't, will Sun still keep it?
