The DEV_BROADCAST_VOLUME structure contains information about a logical volume.
typedef struct _DEV_BROADCAST_VOLUME {
ULONG dbcv_size; ULONG dbcv_devicetype; ULONG dbcv_reserved; ULONG dbcv_unitmask; USHORT dbcv_flags; } DEV_BROADCAST_VOLUME;
typedef DEV_BROADCAST_VOLUME *PDEV_BROADCAST_VOLUME;
Value |
Meaning |
DBTF_MEDIA |
Change affects media in drive. If not set, change affects physical device or drive. |
DBTF_NET |
Indicated logical volume is a network volume. |
Although the dbcv_unitmask member may specify more than one volume in any given message, this does not guarantee that only message is generated for a given event. Multiple system components may independently generate messages for logical volumes at the same time.
