I think the worry is that some future system might have TIDs which do not share the PID space, or are real descriptors (that they need explicit open and close operations). > On a different subject, I'm going to start telling people to use > "syscall(SYS_getrandom)", since I think that's going to be easier than > having asking people to change their Makefiles to link against some > Linux-specific library, but that's a different debate, and I recognize > the glibc folks aren't willing to bend on that one. I think we can reach consensus for an implementation which makes this code unsigned char session_key[32]; getrandom (session_key, sizeof (session_key), 0); install_session_key (session_key); correct. That is, no error handling code for ENOMEM, ENOSYS, EINTR, ENOMEM or short reads is necessary. It seems that several getrandom wrappers currently built into applications do not get this completely right.
