I have something related. I have the following struct in C:

typedef struct
{
  int errnum;
  char errmess[252];
} os_error;

Right now I have this vapified like this:

[CCode (cname == "os_error")]
public struct error
{
  public unowned int errnum;
  public unowned char[] errmess;
}

However, when accessing the error.errmess.length I get compilation
errors (in C,, not in Vala. error: 'os_error' has no member named
'errmess_length1'). I suppose this is due to a problem in the vapi, but
I am not really sure how to tell Vala the length is 252 bytes.

I tried prefixing the errmess member with:
[CCode (array_length_name = "252", array_length_type = "int")]
but that did not seem to make a difference.

Any ideas?

Cheers,
Jan-Jaap
