IntItem* fillIntItem(int* intLocation, char* itemName, int defDeadband); CharItem* fillCharItem(void (*funcPointer)(long*, int**, int*), char* itemName, long tag); [implementation FeeServer core] creates a filled float / integer / char item (NOTE: CharItem requires function pointer) int publish(Item* item); alias: publishFloat(FloatItem* floatItem) int publishInt(IntItem* intItem); int publishChar(CharItem* charItem); [implementation FeeServer core] Publishes a float / integer / char item

7. Normal text - click to edit Interface functions bool setFeeProperty(FeeProperty* prop); [implementation FeeServer core] Allows the CE to set certain FeeProperies during initialize process int allocateMemory(unsigned int size, char type, char* module, char prefixPurpose, void** ptr); [implementation FeeServer core] Lets the FeeServer acquire and handle the memory management int freeMemory(void* addr); [implementation FeeServer core] Frees memory allocated by the FeeServer void signalCEready(int ceState); [implementation FeeServer core] Informs FeeServer, that initialization process has been finished

8. Normal text - click to edit Interface functions int issue(char* command, char** result, int* size); [implementation CE] Hands command data to the CE and accepts possible result data int updateFeeService(char* serviceName); [implementation FeeServer core] Triggers a service update of a published value in the FeeServer void signalFeePropertyChanged(FeeProperty* prop); [implementation CE] Informs the CE about a change in a FeeProperty.

9. Normal text - click to edit Interface functions void createLogMessage(unsigned int type, char* description, char* origin); [implementation FeeServer core] Allows the CE to create log messages (includes them in generell log message handling inside the FeeCom chain  delivery to InterComLayer) void cleanUpCE(); [implementation CE] Deinitializes the ControlEngine (CE) additional helper funtion: void createBenchmark(char* msg); Allows the CE to make a benchmark entry (includes a timestamp)
