I understand.

I am trying to find out what the best way is to "vapify" this
library. There are some naming conventions which are OK within C,
but I would like to go for a more CamelCase style within Vala.

There are some enum-type things defined like this:

typedef bits wimp_error_box_flags;

#define wimp_ERROR_BOX_OK_ICON          ((wimp_error_box_flags) 0x1u)
#define wimp_ERROR_BOX_CANCEL_ICON      ((wimp_error_box_flags) 0x2u)
#define wimp_ERROR_BOX_HIGHLIGHT_CANCEL ((wimp_error_box_flags) 0x4u)

I made these into an enum like this:

public enum ErrorBoxFlags
{
  [CCode (cname = "wimp_ERROR_BOX_OK_ICON")]
  OKIcon = 0x01,
  [CCode (cname = "wimp_ERROR_BOX_CANCEL_ICON")]
  CancelIcon = 0x02,
  [CCode (cname = "wimp_ERROR_BOX_HIGHLIGHT_CANCEL")]
  HighlightCancel = 0x04,
}

Would it be possible to do this somewhat more like this?

[CCode (cprefix = "wimp_ERROR_BOX_")]
public enum ErrorBoxFlags
{
  [CCode (member = "OK_ICON")]
  OKIcon = 0x01,
  [CCode (member = "CANCEL_ICON")]
  CancelIcon = 0x02,
  [CCode (member = "HIGHLIGHT_CANCEL")]
  HighlightCancel = 0x04,
}

(where "member" is something I invented)

Is something like this possible? It would make it a bit more
readable. But maybe there is no point in that for a vapi-file?
