|   Send a security protocol command to a device that receives data and/or the result

 | |
| 
 | |
|   The ReceiveData function sends a security protocol command to the given MediaId.
 | |
|   The security protocol command sent is defined by SecurityProtocolId and contains
 | |
|   the security protocol specific data SecurityProtocolSpecificData. The function
 | |
|   returns the data from the security protocol command in PayloadBuffer.
 | |
| 
 | |
|   For devices supporting the SCSI command set, the security protocol command is sent
 | |
|   using the SECURITY PROTOCOL IN command defined in SPC-4.
 | |
| 
 | |
|   For devices supporting the ATA command set, the security protocol command is sent
 | |
|   using one of the TRUSTED RECEIVE commands defined in ATA8-ACS if PayloadBufferSize
 | |
|   is non-zero.
 | |
| 
 | |
|   If the PayloadBufferSize is zero, the security protocol command is sent using the
 | |
|   Trusted Non-Data command defined in ATA8-ACS.
 | |

|   If PayloadBufferSize is too small to store the available data from the security
 | |
|   protocol command, the function shall copy PayloadBufferSize bytes into the

| 
 | |
|   If the given MediaId does not support security protocol commands, the function shall
 | |
|   return EFI_UNSUPPORTED. If there is no media in the device, the function returns

|   EFI_NO_MEDIA. If the MediaId is not the ID for the current media in the device,
 | |
|   the function returns EFI_MEDIA_CHANGED.
 | |

|   If the security protocol fails to complete within the Timeout period, the function
 | |
|   shall return EFI_TIMEOUT.
 | |
| 
 | |
|   If the security protocol command completes without an error, the function shall

 | |
|   Send a security protocol command to a device.
 | |
| 
 | |
|   The SendData function sends a security protocol command containing the payload
 | |
|   PayloadBuffer to the given MediaId. The security protocol command sent is
 | |
|   defined by SecurityProtocolId and contains the security protocol specific data
 | |
|   SecurityProtocolSpecificData. If the underlying protocol command requires a
 | |
|   specific padding for the command payload, the SendData function shall add padding
 | |
|   bytes to the command payload to satisfy the padding requirements.
 | |
| 
 | |
|   For devices supporting the SCSI command set, the security protocol command is sent
 | |
|   using the SECURITY PROTOCOL OUT command defined in SPC-4.
 | |
| 
 | |
|   For devices supporting the ATA command set, the security protocol command is sent
 | |
|   using one of the TRUSTED SEND commands defined in ATA8-ACS if PayloadBufferSize
 | |
|   is non-zero. If the PayloadBufferSize is zero, the security protocol command is
 | |
|   sent using the Trusted Non-Data command defined in ATA8-ACS.
 | |
| 
 | |
|   If PayloadBuffer is NULL and PayloadBufferSize is non-zero, the function shall
 | |
|   return EFI_INVALID_PARAMETER.
 | |
| 
 | |
|   If the given MediaId does not support security protocol commands, the function
 | |
|   shall return EFI_UNSUPPORTED. If there is no media in the device, the function
 | |
|   returns EFI_NO_MEDIA. If the MediaId is not the ID for the current media in the
 | |
|   device, the function returns EFI_MEDIA_CHANGED.
 | |
| 
 | |
|   If the security protocol fails to complete within the Timeout period, the function
 | |
|   shall return EFI_TIMEOUT.
 | |
| 
 | |
|   If the security protocol command completes without an error, the function shall return
 | |
|   EFI_SUCCESS. If the security protocol command completes with an error, the function
 | |
|   shall return EFI_DEVICE_ERROR.
 | |

|   @param  This                         Indicates a pointer to the calling context.

 | |
|   @param  Timeout                      The timeout, in 100ns units, to use for the execution
 | |
|                                        of the security protocol command. A Timeout value of 0
 | |
|                                        means that this function will wait indefinitely for the
 | |
|                                        security protocol command to execute. If Timeout is greater

 | |

 | |
|   @param  SecurityProtocolSpecificData The value of the "Security Protocol Specific" parameter
 | |
|                                        of the security protocol command to be sent.
 | |
|   @param  PayloadBufferSize            Size in bytes of the payload data buffer.
 | |
|   @param  PayloadBuffer                A pointer to a destination buffer to store the security
