How do I: sigsetjmp inside the handler and then return from the handler such that the signal will be unmasked once I siglongjmp back to this point?

In pseudo code this is sort of the function that I have:

signal_handler(){
    if(sigsetjmp(env[i++]))
        return;
    else
        siglongjmp(env[i]);
}

It's supposed to be the context switch code for user threads in Linux.
