Subject:   Use of sigreturn(2) in longjmp(3).

Hello,

The sigreturn manpage states:

"This system call is used by the trampoline code and longjmp(3) when
returning from a signal to the previously executing program".

Now, I saw the system call in sigtramp.s, but I looked at setjmp.s can't
find how longjmp does this. Am I missing something totally obvious?

Thanks,
Keno
