                                 then EFI_INVALID_PARAMETER is returned.
  @param  VendorGuid             A unique identifier for the vendor.
  @param  Attributes             Attributes bitmask to set for the variable.
  @param  DataSize               The size in bytes of the Data buffer. Unless the EFI_VARIABLE_APPEND_WRITE, 
                                 EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS, or 
                                 EFI_VARIABLE_TIME_BASED_AUTHENTICATED_WRITE_ACCESS attribute is set, a size of zero 
                                 causes the variable to be deleted. When the EFI_VARIABLE_APPEND_WRITE attribute is 
                                 set, then a SetVariable() call with a DataSize of zero will not cause any change to 
                                 the variable value (the timestamp associated with the variable may be updated however 
                                 even if no new data value is provided,see the description of the 
                                 EFI_VARIABLE_AUTHENTICATION_2 descriptor below. In this case the DataSize will not 
                                 be zero since the EFI_VARIABLE_AUTHENTICATION_2 descriptor will be populated). 
  @param  Data                   The contents for the variable.

  @retval EFI_SUCCESS            The firmware has successfully stored the variable and its data as
                                 defined by the Attributes.
  @retval EFI_INVALID_PARAMETER  An invalid combination of attribute bits, name, and GUID was supplied, or the
                                 DataSize exceeds the maximum allowed.
  @retval EFI_INVALID_PARAMETER  VariableName is an empty string.
  @retval EFI_OUT_OF_RESOURCES   Not enough storage is available to hold the variable and its data.
  @retval EFI_DEVICE_ERROR       The variable could not be retrieved due to a hardware error.
  @retval EFI_WRITE_PROTECTED    The variable in question is read-only.
  @retval EFI_WRITE_PROTECTED    The variable in question cannot be deleted.
  @retval EFI_SECURITY_VIOLATION The variable could not be written due to EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS 
                                 or EFI_VARIABLE_TIME_BASED_AUTHENTICATED_WRITE_ACESS being set, but the AuthInfo 
                                 does NOT pass the validation check carried out by the firmware.

  @retval EFI_NOT_FOUND          The variable trying to be updated or deleted was not found.
