// C code can call exported Go functions with their explicit name. But if a C—program wants a function pointer, a gateway function has to be written.
// This is because we can't take the address of a Go function and give that to C—code since the cgo tool will generate a stub in C that should be
// called. The following example shows how to integrate with C code wanting a function pointer of a give type.
