Hi,
what a bad enum: it seems more as an aggregate of constants!
Attached you can find an example vapi, but be aware that I haven't
tested it.
Here a vala snippet to test it:
using SndFile;
int main()
{
var fm = FileMode.READ;
var info = Info ();
var file = File.open ("test.wav", fm, ref info);
return 0;
}
You can look also at the posix.vapi (/usr/share/vala/vapi/posix.vapi).
Regards,
Andrea
