comment:5 by bonefish, 15 years ago

Blocking: 5324 added

(In #5324) ucontext_t and mcontext_t should rather be added as part of implementing SA_SIGINFO (the only feature using these structures), which in turn should be implemented as part of real-time signal support. Cf. #1935.

Blocking: 2695 added

(In #2695) Sorry for not doing this earlier. As discussed via mail, this feature cannot be implemented without real-time signal support. Therefore closing it as duplicate of #1935.

For reference, here's a link to Issue 7 (POSIX.1-2008): ​http://www.opengroup.org/onlinepubs/9699919799/functions/V2_chap02.html#tag_15_04_02

The summary still points to Issue 6 (POSIX.1-2004).

I added a wiki page detailing on the signal related issues and suggesting implementation hints. I'll see, if I can start working on the implementation in the next days.
