Function USBDiskSCSICommand

USBDiskSCSICommand can be used to send an arbitrary SCSI command to a USB disk:

int USBDiskSCSICommand(RTUDiskData * Device, 
                       const BYTE  * SCSIPacket, 
                       UINT          CmdLen, 
                       int           IsRead, 
                       void        * Data, 
                       UINT          Len);

Parameters

Device

Pointer to an RTUDiskData structure associated with the desired disk (see USBDiskInitDevice).

SCSIPacket

Pointer to an SCSI command packet to send to the device.

CmdLen

Size in bytes of the SCSI command packet pointed to by parameter SCSIPacket.

IsRead

0 if the data pointed to by parameter Data must be sent to the device and none-zero otherwise.

Data

Pointer to data to be sent to the device or a pointer to a buffer to receive data from the device. If no data is exchanged, NULL may be specified.

Len

Size in bytes of the data/buffer pointed to by Data. When Data is NULL, this parameter must be zero.

return value

The number of bytes transferred in the data stage or a negative class specific error code or a standard error code on failure.
