/* This is used from only one place: dl-misc.c:_dl_debug_vdprintf.

   Hence it's in a header with the expectation it will be inlined.

   This is writev, but with a constraint added and others loosened:

   1. Under RTLD_PRIVATE_ERRNO, it must not clobber the private errno

      when another thread holds the dl_load_lock.

   2. It is not obliged to detect and report errors at all.

   3. It's not really obliged to deliver a single atomic write

      (though it may be preferable).  */
