>DESCRIPTION</H2
><P
>RTLinux currently supports two types of User-Level signals --
<TT
CLASS="LITERAL"
>interrupts</TT
> and <TT
CLASS="LITERAL"
>timers</TT
>. In functions
such as <TT
CLASS="FUNCTION"
>rtlinux_sigaction</TT
>(3) and
<TT
CLASS="FUNCTION"
>rtlinux_sigaddset</TT
>(3) you can use the following defines
for the <TT
CLASS="PARAMETER"
><I
>signum</I
></TT
>.</P
><P
><TT
CLASS="LITERAL"
>RTLINUX_SIGIRQ</TT
><I
CLASS="EMPHASIS"
>x</I
> signals refer to
interrupt-driven signals, where <I
CLASS="EMPHASIS"
>x</I
> is the IRQ number.
Currently any IRQ supported by Linux can be used in RTLinux signals, and <I
CLASS="EMPHASIS"
>x</I
> designates the IRQ number, which can be any number from 0 to
one less than the maximum number of IRQs (currently defined as
<TT
CLASS="LITERAL"
>NR_IRQS</TT
>).</P
><P
><TT
CLASS="LITERAL"
>RTLINUX_SIGTIMER</TT
><I
CLASS="EMPHASIS"
>x</I
> signals can be used
to setup real-time timers in userspace as described in
<TT
CLASS="FUNCTION"
>rtlinux_sigaction</TT
>(3). <I
CLASS="EMPHASIS"
>x</I
> can be any
number from 0 to 15.</P
