I mean just what I said: rt_tgsigqueueinfo's treatment of the siginfo_t should match rt_sigqueueinfo's. Make it match rt_sigqueueinfo today and make sure that if rt_sigqueueinfo changes, then rt_tgsigqueueinfo will change to match. > Is there anything else which stands in the way of getting the > rt_tgsigqueueinfo interface merged ? I don't see any problem. But you should at least make sure that Ulrich likes the syscall interface for implementing pthread_sigqueue or whatever it will be.
