I'm pretty sure all uses of "PID" in the man page for set_tid_address should instead read "TID". While the issue is present in many man pages and should probably be fixed globally, this one is particularly confusing because "TID" is also used in the function, argument, and task attribute names to mean the exact same thing. The word "process" is also used misleadingly, "For each process...". The most important fix is to clarify that the return value is the TID of the caller, not the PID. But I think it should just all be fixed.
