57 Request Packet is greater than Timeout.\r
58 @param[in, out] SenseData A pointer to sense data that was generated by\r
59 the execution of the SCSI Request Packet. This\r
60 buffer must be allocated by the caller.\r
61 If SenseDataLength is 0, then this parameter is\r
62 optional and may be NULL.\r

9ccbe812 64 the SenseData buffer. On output, a pointer to\r
d5954c61 65 the number of bytes written to the SenseData buffer. \r

465 and may be NULL. \r

467 the DataBuffer buffer. On output, a pointer\r
468 to the number of bytes written to the DataBuffer\r
469 buffer. \r
