!!NAME


sigreturn - return from signal handler and cleanup stack frame
!!SYNOPSIS


__int sigreturn(unsigned long__
''__unused''__);__
!!DESCRIPTION


When the Linux kernel creates the stack frame for a signal
handler, a call to __sigreturn__ is inserted into the
stack frame so that the the signal handler will call
__sigreturn__ upon return. This inserted call to
__sigreturn__ cleans up the stack so that the process can
restart from where it was interrupted by the
signal.
!!RETURN VALUE


__sigreturn__ never returns.
!!WARNING


The __sigreturn__ call is used by the kernel to implement
signal handlers. It should __never__ be called directly.
Better yet, the specific use of the ''__unused'' argument
varies depending on the architecture.
!!CONFORMING TO


__sigreturn__ is specific to Linux and should not be used
in programs intended to be portable.
