 *  \version  1.6
 *  \author   GenTL Subcommittee
 *  \date     2019
 *
 *  \par Version history
 *  \li Version 0.1.0   First official version from the meeting in Pilsen
 *  \li Version 0.1.1   rst (SI) 0.4.160
 *                      - added _E_INTERFACE_INFO_CMD_LIST_T_ enum name
 *                      - added _E_DEVICE_ACCCESS_STATUS_TYPE_T_ to be used
 *                      with the /a IFGetDeviceInfo and DevGetInfo
 *                      - rename of the enum value DEVICE_INFO_ACCESSMODE to
 *                      DEVICE_INFO_ACCESS_STATUS which now refers to
 *                      _E_DEVICE_ACCCESS_STATUS_TYPE_T_
 *                      - added Timeout parameter to update interface list and
 *                      device list.
 *  \li Version 0.1.2   - change datatype of timeout parameter of
 *                      TLUpdateInterfaceList and IFUpdateDeviceList to
 *                      uint64_t to match with the timeout in the event object.
 *                      - changed all enums to have a typedef to uint32_t
 *                      with them to allow custom ids
 *                      - changed type of string constants to be char * instead

 *                      - adjusted parameter names to be closer aligned with
 *                      the standard text
 *                      - changed typedefs for enums from uint32_t to int32_t
