What I've done:
[Compact, CCode (cname = "void")]
public class Handle {
// ...
}
[CCode (has_target = false)]
public delegate void DescriptorConnectPort(Handle? instance, ulong
port, ref double dataLocation);
[CCode (copy_function="", destroy_function="")]
public struct Descriptor
{
[CCode (cname = "UniqueID")]
public ulong unique_id;
[CCode (cname = "Label")]
public unowned string label;
[CCode (cname = "Properties")]
public Properties properties;
[CCode (cname = "Name")]
public unowned string name;
[CCode (cname = "Maker")]
public unowned string maker;
[CCode (cname = "Copyright")]
public unowned string copyright;
[CCode (cname = "PortCount")]
public ulong port_count;
[CCode (cname = "PortDescriptors")]
public const PortDescriptor[] port_descriptors;
[CCode (cname = "PortNames")]
public unowned string[] port_names;
[CCode (cname = "PortRangeHints")]
public const PortRangeHint[] port_range_hints;
[CCode (cname = "ImplementationData")]
public void[] implementation_data;
public Handle? instantiate(Handle? descriptor, ulong sampleRate);
public DescriptorConnectPort? connect_port;
public void activate(Handle? instance);
public void run(Handle? instance, ulong sampleCount);
public void run_adding(Handle? instance, ulong sampleCount);
public void set_run_adding_gain(Handle? instance, Data gain);
public void deactivate(Handle? instance);
public void cleanup(Handle? instance);
}
but...
