That gives me the following error.
libzmq.vapi:80.34-80.41: error: The type name `GLib.Fun' could not be found
public Msg.data(uint8[] data, GLib.Fun? ffn = null);
Although, I tried:
[CCode (cname = "zmq_free_fn", type = "void (*)(void *, void *)")]
public delegate void free_fn(void *data);
with the constructor:
[CCode (cname = "zmq_msg_init_data")]
public Msg.data(owned uint8[] data, free_fn? ffn = null);
And it now compiles and runs. It seems to work properly now. I have the
hello world example working.
Although, in the constructor the data is type uint8[], and in it's free
function free_fn it's a void*. Is there any way to correct this?
Thanks,
~Lewis
