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

     none

AVAILABILITY

     Linux 1.0+
