There is one more issue, and that is an atomicy issue. We want the
new signal mask to be set simultaniously with the restoration of the
context (or most of it). This means that all signals must be masked
temporarily while restoring the context. But don't worry about it,
I can handle that part as well. It does mean an extra system call
but that isn't our concern at the moment.
so the sequence is something like
sigprocmask(SIG_BLOCK, ALL, &ocntx->uc_sigmask);
swap registers+stacks
sigprocmask(SIG_SETMASK, &ncntx->us_sigmask, NULL);
for swapcontext.
am i wrong or is setcontext essentially
swapcontext(&tmpcontext, newcntx); ?
cheers
