DESCRIPTION    [Toc]    [Back]

     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).
