<p class="commentary firstcommentary"><a id="SP9" class="paragraph-anchor"></a><b>§9. </b>So, then, time to write some more of the C library. We are going to need to
|
||||
define the macros <span class="extract"><span class="extract-syntax">I7BYTE_0</span></span> to <span class="extract"><span class="extract-syntax">I7BYTE_3</span></span>, and also the functions <span class="extract"><span class="extract-syntax">i7_read_word</span></span>
|
||||
and <span class="extract"><span class="extract-syntax">i7_read_byte</span></span>, used just above. But we start with the function which resets
|
||||
memory to its initial state when a process begins, and with the stack empty.
|
||||
</p>
|
||||
|
||||
<p class="commentary">Note that we fill in ten bytes of the 64-byte header block of memory:
|
||||
</p>
|
||||
|
||||
<ul class="items"><li>● The Release number as a big-endian 16-bit value at <span class="extract"><span class="extract-syntax">0x34-0x35</span></span>;
|
||||
</li><li>● The Serial code as six ASCII characters (in practice digits) at <span class="extract"><span class="extract-syntax">0x36-0x3B</span></span>.
|
||||
</li></ul>
|
||||
<p class="commentary">We carefully defined those two constants, if they exist, before the inclusion point of
|
||||
the C library in order that the conditional compilations in <span class="extract"><span class="extract-syntax">i7_initialise_memory_and_stack</span></span>
|
||||
will work correctly. See <a href="5-cnm.html#SP7" class="internal">CNamespace::declare_constant</a>.
|
||||
</p>
|
||||
|
||||
<p class="commentary">The rest of the header area remains all zeros.

memory to its initial state when a process begins, and with the stack empty.

(*) The Serial code as six ASCII characters (in practice digits) at |0x36-0x3B|.

We carefully defined those two constants, if they exist, before the inclusion point of

the C library in order that the conditional compilations in |i7_initialise_memory_and_stack|
|

will work correctly. See //CNamespace::declare_constant//.
