DeviceDsmValidateOutput function (ntddstor.h)
The DeviceDsmValidateOutput function validates the output for a data set management (DSM) operation.
Syntax
BOOLEAN DeviceDsmValidateOutput(
PDEVICE_DSM_DEFINITION Definition,
PDEVICE_DSM_OUTPUT Output,
ULONG OutputLength
);
Parameters
Definition
Pointer to a DEVICE_DSM_DEFINITION structure that defines the operation.
Output
Pointer to the DEVICE_DSM_OUTPUT structure of the operation.
OutputLength
The length, in bytes, of the entire output buffer.
Return value
Returns TRUE if the output is valid, or FALSE otherwise.
Remarks
The output is returned in the payload of an IOCTL_STORAGE_MANAGE_DATA_SET_ATTRIBUTES request. Before extracting the output, the caller should first call DeviceDsmValidateOutput to ensure that the output is valid based on the operation's Definition and Output (whose Action members must match), including the DEVICE_DSM_OUTPUT structure that Output points to, and the output block, if any, that follows the DEVICE_DSM_OUTPUT structure.
See Data Set Management Overview for more details on handling a DSM.
