IoCheckQuerySetVolumeInformation function (ntifs.h)
The IoCheckQuerySetVolumeInformation routine checks the validity of the parameters for either a query or set volume information operation.
Syntax
NTSTATUS IoCheckQuerySetVolumeInformation(
FS_INFORMATION_CLASS FsInformationClass,
ULONG Length,
BOOLEAN SetOperation
);
Parameters
FsInformationClass
A FS_INFORMATION_CLASS enum value that specifies the information class to be checked.
Length
Size, in bytes, of the buffer required for the specified information operation.
SetOperation
Boolean value that specifies the operation type. If SetOperation is TRUE, the operation is a set volume operation; if FALSE, it is a query volume operation.
Return value
IoCheckQuerySetVolumeInformation returns STATUS_SUCCESS if the parameters are valid; otherwise, it returns one of the following error codes.
| Return Code | Description |
|---|---|
| STATUS_INVALID_INFO_CLASS | The value specified in FsInformationClass is not a valid information class. |
| STATUS_INFO_LENGTH_MISMATCH | The buffer size specified in Length is smaller than the buffer size required for the specified volume operation. |
Remarks
IoCheckQuerySetVolumeInformation is used primarily by network servers running in kernel mode since no such parameter validity checking is done in the normal path.
Requirements

|---|---|
| Target Platform | Windows |
