<p><strong>Description</strong><br>
<code>diprintf</code> and <code>vdiprintf</code> are similar to <code>dprintf</code> and <code>vdprintf</code>,
except that only integer format specifiers are processed.
</p>
<p>The functions <code>_diprintf_r</code> and <code>_vdiprintf_r</code> are simply
reentrant versions of the functions above.
</p>
<br>
<p><strong>Returns</strong><br>
Similar to <code>dprintf</code> and <code>vdprintf</code>.
</p>
<br>
<p><strong>Portability</strong><br>
This set of functions is an integer-only extension, and is not portable.
</p>
<p>Supporting OS subroutines required: <code>sbrk</code>, <code>write</code>.
</p>
