The FS_BPIO_INFO structure provides information about the BypassIO state of the volume.
Syntax
typedef struct _FS_BPIO_INFO {
ULONG ActiveBypassIoCount;
USHORT StorageDriverNameLen;
WCHAR StorageDriverName[32];
} FS_BPIO_INFO, *PFS_BPIO_INFO;
Members

The number of BypassIO-enabled files that are currently open.
StorageDriverNameLen
Receives the length of the string stored in StorageDriverName, in characters.
StorageDriverName[32]
