<H3>3.4.9 Watchdog Data Types</H3>
<p>
When a watchdog expires, the callback function with this
type is called:
</p>
<pre>
typedef void (*wdentry_t)(int argc, ...);
</pre>
<p>
Where argc is the number of uint32 type arguments that follow.
</p>
The arguments are passed as uint32 values.
For systems where the sizeof(pointer) &lt; sizeof(uint32), the
following union defines the alignment of the pointer within the
uint32. For example, the SDCC MCS51 general pointer is
24-bits, but uint32 is 32-bits (of course).
</p>
<pre>
union wdparm_u
{
void *pvarg;
uint32 *dwarg;
};
typedef union wdparm_u wdparm_t;
</pre>
<p>
For most 32-bit systems, pointers and uint32 are the same size
For systems where sizeof(pointer) > sizeof(uint32), we will
have to do some redesign.
