NAME
     sigreturn - returns from a signal handler.

SYNOPSIS
     struct sigreturna {
          irix5_sigcontext_t  *scp;
          void           *ucp;
          sysarg_t       signo;
     };

     int sigreturn(struct sigreturna *uap)

DESCRIPTION
     Can only be called from within the kernel.

     The sigreturn system call is used by the kernel to return from signal
     handlers.  It restores the context of the process which received the
     signal.

     The general behaviour of this system call is very similar to longjmp(2).
