A quick question concerning "sigvec".

The UNIX manual shows the user's interrupt handler as:

    handler (sig, code, scp)

	int sig, code;
	struct sigcontext *scp;

According to the manual:

"Scp is a pointer to the sigcontext structure used to restore
the context from before the signal."

So how do I use "scp"???

Can I use it to explicitly restore the context to return where I
was before the signal?
If so, then I should be able to store it somewhere for later use,
then use it at some time in the future to go back to where I was
before the signal occurred.  Does this make sense?
