so that a specific emulation has the oportunity to filter out some signals. if sigfilter returns 0, then no signal is sent by kpsignal2(). There is another place where signals can be generated: trapsignal. Since this function is already an emulation hook, no call to the sigfilter hook was introduced in trapsignal. This is needed to emulate the softsignal feature in COMPAT_DARWIN (signals sent as Mach exception messages) |
