cli(9) Kernel Functions cli(9)NAME
cli, sti - disable/enable interrupts
SYNOPSIS
#include <asm/system.h>
extern void cli()
extern void sti()DESCRIPTION
The cli function causes interrupts to be blocked on the host, so that
following critical code may run uninterrupted. The sti function enables
interrupts again.
Although it is possible to use cli/sti pairs to protect critical code,
it is best to use cli with the save_flags macro. See save_flags (9).
RETURN VALUE
