/* 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). */
