|Has a Patch:||no||Platform:||All|
Haiku currently supports default POSIX signal handlers with no additional signal info, and BeOS' derived signal handlers with additional register access and user-supplied data.
Not yet supported are the extended POSIX signal handlers with
ucontext_t arguments. Some parts thereof are already prepared in the headers but commented out since not implemented on the kernel side.
I had recently submitted a first draft patch for the x86 kernel side signal frame setup. Some fields are not initialized yet, and some information is not (yet) easily obtainable according to Ingo.
