In looking into implementing a Gnulib approximation to or wrapper forthe getrandom proposal, I noticed that the most recent (Sept. 12)version the proposed getrandom returns int (like Solaris 11), whereasthe previous version (Sept. 8) returned ssize_t (like 'read'). From theGNU point of view ssize_t makes more sense, as it avoids an arbitrary 2GiB limit on 64-bit hosts. I don't recall this change being discussed soI thought I'd ask what's up.
