pthread_setname_np documentation

[Eric Gallager]

Hi, I'm writing about gnulib's documentation for pthread_setname_np:
https://www.gnu.org/software/gnulib/manual/html_node/pthread_005fsetname_005fnp.html
It mentions NetBSD 10.0 as a platform where the function has a
different signature, however, I recently discovered that there is
another platform where this is true: on my version of macOS, the
function exists, and takes just 1 argument: a string for the name of
the thread. Here's the contents of my system's manpage for it:

PTHREAD_SETNAME_NP(3)
                                Library Functions Manual

PTHREAD_SETNAME_NP(3)

PTHREAD_SETNAME_NP(3)

I notice that the gnulib documentation page says that Mac OS X 10.5
didn't have this function, so I'm guessing it must have been
introduced in 10.6? I'm not quite sure where to find the history of
it, though...
