Thanks, that's what I needed to hear ;-)

I'm working on a LibSndFile wrapper, that's the reason for learning
wrapping.
I've got the a small part working, but not much (yet). I'm compiling with
valac --save-temps,
and analysing the output to work out where my errors are.

I'm getting stuck on "enum" types, that are *NOT* in a namespace.
Eg: the name of the enum IS what to call that in the output C file.

enum
{    /* True and false */
    SF_FALSE    = 0,
    SF_TRUE        = 1,
    /* Modes for opening files. */
    SFM_READ    = 0x10,
    SFM_WRITE    = 0x20,
    SFM_RDWR    = 0x30,
    SF_AMBISONIC_NONE        = 0x40,
    SF_AMBISONIC_B_FORMAT    = 0x41
} ;

Is the one I'm stuck on now. I tried this in the .vapi:
class Sndfile
{ // all other functions ommitted for brevity
    [CCode (cname="")]
    public enum FileMode
    {    /* True and false */
        SF_FALSE    = 0,
        SF_TRUE        = 1,
        /* Modes for opening files. */
        SFM_READ    = 0x10,
        SFM_WRITE    = 0x20,
        SFM_RDWR    = 0x30,
        SF_AMBISONIC_NONE        = 0x40,
        SF_AMBISONIC_B_FORMAT    = 0x41
    }
}

but the C output goes like so  SNDFILE_FILE_MODE_SFM_READ  while I want
SFM_READ.
I hoped that the  cname=""  would clear the SNDFILE_FILE_MODE_  from the
start but it didnt..

Any pointers as to how to do this? Cheers, -Harry
