Members
- pdp_PlugNumber

Defines whether the given plug is an input or an output plug. Will be either STREAM_PLUG_INPUT or STREAM_PLUG_OUTPUT. - pdp_MediaType
Type of medium this plug was defined as handling. A value from the STREAM_MediaType enumeration. - pdp_SubunitPlugID
Plug identifier value of the subunit-specific plug that is associated with this serial bus plug. - pdp_Plug
Plug handle for this particular plug, as returned from IOCTL_UNIT_ALLOCATE_LOCAL_PLUG. - vvqs_PredefinedPlugs
Array that is completed with the currently defined plug descriptions for the virtual VCR driver. - vvqs_NumPredefinedPlugs
