Go struct types are not supported; use a C struct type.
Go array types are not supported; use a C pointer.

Go functions that take arguments of type string may be called with the
C type _GoString_, described above. The _GoString_ type will be
automatically defined in the preamble. Note that there is no way for C
code to create a value of this type; this is only useful for passing
string values from Go to C and back to Go.
