<h5>Overview:</h5>
<p> The '<tt>getresult</tt>' instruction is used to extract individual values
from multiple values returned by a '<tt><a href="#i_call">call</a></tt>'
or '<tt><a href="#i_invoke">invoke</a></tt>' instruction.

<h5>Arguments:</h5>
The '<tt>getresult</tt>' instruction takes a return value as first argument.
The value must have <a href="#t_struct">structure type</a>. The second argument
