<H2>Pointers to Functions</H2>
<p>
Okay, just what in the heck does SWIG do with a declaration like this?
<blockquote>
<pre>
int do_op(int a, int b, int (*op)(int, int));
</pre>
</blockquote>
Well, it creates a wrapper as usual. Of course, that does raise some
questions about the third argument (the pointer to a function).
<p>
In this case, SWIG will wrap the function pointer as it does for all
other pointers. However, in order to actually call this function from
a Go program, you will need to pass some kind of C function pointer
object. In C, this is easy, you just supply a function name as an
argument like this:
<blockquote>
<pre>
/* Some callback function */
int add(int a, int b) {
return a+b;
}
...
int r = do_op(x,y,add);
</pre>
</blockquote>
To make this work with SWIG, you will need to do a little extra work.
Specifically, you need to create some function pointer objects using
the %constant directive like this:
<blockquote>
<pre>
%constant(int (*)(int,int)) ADD = add;
</pre>
</blockquote>
Now, in a Go program, you would do this:
<blockquote>
<pre>
int r = do_op(x,y, example.ADD)
</pre>
</blockquote>
where <tt>example</tt> is the module name.
<h2>An Example</h2>
Here are some files that illustrate this with a simple example:
<ul>
<li><a href="example.c">example.c</a>
<li><a href="example.h">example.h</a>
<li><a href="example.i">example.i</a> (SWIG interface)
<li><a href="runme.go">runme.go</a> (Sample program)
</ul>
<h2>Notes</h2>
<ul>
<li>The value of a function pointer must correspond to a function
written in C or C++. It is not possible to pass an arbitrary Go
function in as a substitute for a C function pointer.
</ul>
