SIGRETURN(2) Linux Programmer's Manual SIGRETURN(2)
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 upon
return from the signal handler, sigreturn() will be called.
This sigreturn() call undoes everything that was done--changing the process's signal mask, switching stacks (see sigaltstack(2))--in order
to invoke the signal handler: it restores the process's signal mask, switches stacks, and restores the process's context (registers, pro-
cessor flags), so that the process directly resumes execution at the point where it was interrupted by the signal.
RETURN VALUE
sigreturn() never returns.
FILES
/usr/src/linux/arch/i386/kernel/signal.c
/usr/src/linux/arch/alpha/kernel/entry.S
CONFORMING TO
sigreturn() is specific to Linux and should not be used in programs intended to be portable.
NOTES
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.
SEE ALSO
kill(2), sigaltstack(2), signal(2), signal(7)
