Hmmm... POSIX.1 says it should be socklen_t, but as you point out,
the Linux/glibc reality is size_t, and has been so at least as far
back as glibc 2.0. So, I've raised a glibc bug:
http://sourceware.org/bugzilla/show_bug.cgi?id=2448
And in the meantime, I have added a NOTE to these two pages
pointing out that glibc actually uses size_t instead of
socklen_t. (I have left the structure defintion the same,
because it is what POSIX specifies, and merely pointed
out the deviation under the NOTE).
The man-pages changes will be in upstream 2.26.
Thanks for your report Paul.
Cheers,
Michael
