NAME
cli, sti − disable/enable interrupts
SYNOPSIS
#include
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
none
AVAILABILITY
Linux 1.0+
