There is no API or ioctl to query event channel status, it is only present in xenctrl.h The C union is mapped to an OCaml variant exposing just the value from the correct union tag. This causes the xc bindings to now depend on evtchn to get a useful API for EVTCHNSTAT_virq. The information provided here is similar to 'lsevtchn', but rather than parsing its output it queries the underlying API directly.
