MFC: a lot of manpage fixes from HEAD.

- Add two new system calls: preadv() and pwritev() which are like readv()

2005-07-07T18:17:55+00:00

  and writev() except that they take an additional offset argument and do
  not change the current file position.  In SAT speak:
  preadv:readv::pread:read and pwritev:writev::pwrite:write.
- Try to reduce code duplication some by merging most of the old
  kern_foov() and dofilefoo() functions into new dofilefoo() functions
  that are called by kern_foov() and kern_pfoov().  The non-v functions
  now all generate a simple uio on the stack from the passed in arguments
  and then call kern_foov().  For example, read() now just builds a uio and
  calls kern_readv() and pwrite() just builds a uio and calls kern_pwritev().

read(), pread(), write(), and pwrite() return EINVAL if they are asked

for more than INT_MAX bytes.

Nitpicking on grammar.

Reword the last change a bit, add mdoc(7) markup.

Discussed with:	bde

Explain it is a negative offset that EINVAL may indicate.

2004-10-16T09:53:35+00:00

Now readers won't get an impression that pointing to beyond
the current end of file will result in EINVAL.

Mechanically kill hard sentence breaks.

Markup, grammar, and spelling fixes.

The maximum value of iovcnt is IOV_MAX, not 16.
