IOCTL_STORAGE_PROTOCOL_COMMAND IOCTL

A driver can use IOCTL_STORAGE_PROTOCOL_COMMAND to pass vendor-specific commands to a storage device.

Major code

IRP_MJ_DEVICE_CONTROL

Input buffer

None.

Input buffer length

None.

Output buffer

The driver returns the results of the vendor-specific command to the buffer at Irp->AssociatedIrp.SystemBuffer. Cast the structure returned to a STORAGE_PROTOCOL_COMMAND and check its ReturnStatus field to determine the status of the command request.

Output buffer length

Parameters.DeviceIoControl.OutputBufferLength in the I/O stack location indicates the size, in bytes, of the parameter buffer, which must be >= sizeof(STORAGE_PROTOCOL_COMMAND).

Status block

The Information field is set to the number of bytes returned. The Status field is set to STATUS_SUCCESS, or possibly to STATUS_INSUFFICIENT_RESOURCES.
