[Vala] array_length_cname not working?

[Alexander Krivács Schrøder <alexschrod gmail com>]

Hi.

I have a property in my class like so:

public Line[] lines
{
    owned get
    {
        ...
    }
}

The signature of the generated C code looks like this:

Line** class_name_get_lines (ClassName* self, int* result_length1);

I'm not particularly fond of the "result_length1" parameter name, so I
looked up documentation on the CCode attribute, and it has a setting
named "array_length_cname" that looked like it was just what I was
looking for. Sadly, whether I placed it on the attribute or the get
itself, the generated code would still use the parameter name
"result_length1." That is, neither of these two worked:

[CCode(array_length_cname = "count")]
public Line[] lines
{
    owned get
    {
        ...
    }
}


public Line[] lines
{
    [CCode(array_length_cname = "count")]
    owned get
    {
        ...
    }
}

An interesting observation is that the .vapi file generated retains the
CCode attribute in the location I placed it, but the .h file generated
still calls it "result_length1." In other words, placing either of those
CCode attributes creates an incompatibility between the .vapi and the .h
from valac.

Since this isn't working, I have a feeling I'm going about this all
wrong... any hints or pointers?
