[Vala] Too many arguments in generated code

[tomw <tomw ubilix com>]

Hi,

I'm about to port the Skeltrack [1] skeleton tracker to Vala. So far
everything works fine, except getting the actual joints from the joint
list. The code in C is pretty straight forward:

head = skeltrack_joint_list_get_joint (list,
                                       SKELTRACK_JOINT_ID_HEAD);

which in Vala is:

var head = JointList.get_joint(list, Skeltrack.JointId.HEAD);

The generated code from Vala however looks like:

skeltrack_joint_list_get_joint (list, SKELTRACK_JOINT_ID_HEAD, &_tmp2_);
head = _tmp2_;

which makes the compiler complain that there are too many arguments.

The respective part in the vapi looks like:

[CCode (cheader_filename = "skeltrack.h")]
        [SimpleType]
        public class JointList {
                public static void free (Skeltrack.JointList list);
                public static Skeltrack.Joint get_joint (Skeltrack.JointList list, Skeltrack.JointId id);
        }


Any clue why that happens?

thanks,
