When <tt>numinputs</tt> is set to 0, the argument is effectively ignored and cannot be supplied from the target language.
The argument is still required when making the C/C++ call and the above typemap
shows the value used is instead obtained from a locally declared variable called <tt>temp</tt>.
Usually <tt>numinputs</tt> is not specified, whereupon the default value is 1, that is, there is a one to one mapping of the number of arguments when used from the target language to the C/C++ call.
