Members

vve_Event
Event that occurred. The possible events are shown in the VVCR_EVENT_Type enumeration.
vve_Union.PlugStateChange.psc_PlugNumber
Numerical serial bus plug number of the plug whose state has changed.
vve_Union.PlugStateChange.psc_Direction
Defines whether the given plug is an input or an output plug. Will be either STREAM_PLUG_INPUT or STREAM_PLUG_OUTPUT.
vve_Union.PlugStateChange.psc_PlugState
Boolean value that implies whether there is at least one connection established to this plug. If FALSE, no connections currently exist. If TRUE, at least one connection exists.
vve_Union.PlugStateChange.psc_MediaType
Type of medium this plug was defined as handling. The possible events are shown in the STREAM_MediaType enumeration.
vve_Union.PlugStateChange.psc_Plug
Plug handle for this particular plug, as returned from IOCTL_UNIT_ALLOCATE_LOCAL_PLUG.
vve_Union.PlugStateChange
Information on the plug state change.
vve_Union.PlayRequest.pr_RequestIdentifier
Identifier that, when the application has completed processing this request, should be used to notify the virtual VCR driver of the completion state. An argument to IOCTL_VVCR_COMPLETE.
vve_Union.PlayRequest.pr_PlayMode
Type of play mode being requested, as defined by the AV/C Tape Recorder/Player Subunit Specification.
vve_Union.PlayRequest
Information on the play request.

vve_Union.WindRequest.wr_WindMode
Type of wind mode being requested, as defined by the AV/C Tape Recorder/Player Subunit Specification.
vve_Union.WindRequest
Information on the wind request.
vve_Union.RelativeTimeCounter.rtc_RequestIdentifier
Identifier that, when the application has completed processing this request, should be used to notify the virtual VCR driver of the completion state. An argument to IOCTL_VVCR_COMPLETE.
vve_Union.RelativeTimeCounter.rtc_Hour
Hour value of the time counter that the virtual VCR has been requested to seek to. The range is 0 to 99.
vve_Union.RelativeTimeCounter.rtc_Minute
Minute value of the time counter that the virtual VCR has been requested to seek to. The range is 0 to 99.
vve_Union.RelativeTimeCounter.rtc_Second
Second value of the time counter that the virtual VCR has been requested to seek to. The range is 0 to 99.
vve_Union.RelativeTimeCounter.rtc_Frame
Frame value of the time counter that the virtual VCR has been requested to seek. The appropriate range is 0 to a value dictated by the type of medium being streamed.
vve_Union.RelativeTimeCounter.rtc_Negative
If set to TRUE, the requested time counter is to be considered negative. If set to FALSE, the requested time counter is to be considered positive.
vve_Union.RelativeTimeCounter
Information on the relative time counter.
vve_Union.TimeCode.tc_RequestIdentifier
Identifier that, when the application has completed processing this request, should be used to notify the virtual VCR driver of the completion state. An argument to IOCTL_VVCR_COMPLETE.

Second value of the time code that the virtual VCR has been requested to seek. The range is 0 to 99.
vve_Union.TimeCode.tc_Frame
Frame value of the time code that the virtual VCR has been requested to seek. The appropriate range is 0 to a value dictated by the type of media being streamed.
vve_Union.TimeCode
Information on the time code.
vve_Union.AbsoluteTrackNumber.atn_RequestIdentifier
Identifier that, when the application has completed processing this request, should be used to notify the virtual VCR driver of the completion state. An argument to IOCTL_VVCR_COMPLETE.
vve_Union.AbsoluteTrackNumber.atn_TrackNumber
Absolute track number on the tape that the virtual VCR has been requested to seek to. For more information on the format of this value, see the AV/C Tape Recorder/Player Subunit Specification.
vve_Union.AbsoluteTrackNumber
Information on the absolute track number.
vve_Union
Set of separate structures, one for each potential value in vve_Event.
