Re: [PATCH v7 3/5] Add preadv and pwritev system calls.

The application-visible interface provided by glibc should look like
this to be compatible to the existing implementations in the *BSD family:

 ssize_t preadv(int d, const struct iovec *iov, int iovcnt, off_t offset);
 ssize_t pwritev(int d, const struct iovec *iov, int iovcnt, off_t offset);

I earlier asked if you could provide some userspace example code using
this API.  If there was a response, I missed it.  Could you please
provide some working test using this interface.

I had some ptrs in the patch series intro text.
Standalone test app is attached now.

cheers,
