<p>
<b>Note</b>
<p>
The diameter and shape of the via depend on the layer for which they shall be retrieved,
because they may be different in each layer depending on the <a href=127.htm>Design Rules</a>.
If one of the <a href=178.htm>layers</a> LAYER_TOP...LAYER_BOTTOM, LAYER_TSTOP or LAYER_BSTOP
is given as the index to the diameter or shape data member, the resulting value will be calculated
according to the Design Rules. If LAYER_VIAS is given, the raw value as defined in the via will
be returned.
<p>
Note that <tt>diameter</tt> and <tt>shape</tt> will always return the diameter or
shape that a via would have in the given layer, even if that particular via doesn't
cover that layer (or if that layer isn't used in the layer setup at all).
<p>
<tt>start</tt> and <tt>end</tt> return the layer numbers in which that via starts and
ends. The value of <tt>start</tt> will always be less than that of <tt>end</tt>.
<p>
<tt>drillsymbol</tt> returns the number of the drill symbol that has been assigned
to this drill diameter (see the manual for a list of defined drill symbols).
A value of <tt>0</tt> means that no symbol has been assigned to this drill diameter.
<p>
<b>Example</b>
<pre>
board(B) {
B.signals(S) {
S.vias(V) {
printf("Via: (%d %d)\n", V.x, V.y);
}
}
}
