ZWay: getting the device list.

Back after a while... and a son!

Here is a piece of code that can be used with the latest version of the ZWay library. It makes it possible to retrieve the Z-Wave device list and display the device names and associated XML file (each recognized device can be associated to an XML that contains a bunch of meta-data: name, description etc.).

 int main(int argc, char ** argv) {  
      ZWay theZWay;  
      ZWError result;  
      memset(&theZWay, 0, sizeof(theZWay));  
      result = zway_init(&theZWay, "/dev/ttyAMA0",  
                "/home/pi/src/razberry-proxy/config",  
                "/home/pi/src/razberry-proxy/translations",  
                "/home/pi/src/razberry-proxy/ZDDX", stdout, Warning);  
      if (result == NoError) {  
           result = zway_start(theZWay, &terminationCb);  
           if (result == NoError) {  
                printf("Discovering...\n");  
                result = zway_discover(theZWay);  
                if (result == NoError) {  
                     printf("Getting device list\n");  
                     ZWDevicesList devicesList = zway_devices_list(theZWay);  
                     ZWBYTE * pDeviceNodeId = devicesList;  
                     if (pDeviceNodeId != NULL) {  
                          while (*pDeviceNodeId != 0) {  
                               printf("Device node ID: %d\n", *pDeviceNodeId);  
                               if (*pDeviceNodeId > 1) {  
                                    ZGuessedProduct * productsList = zway_device_guess(theZWay, *pDeviceNodeId);  
                                    struct _ZGuessedProduct * pProduct = *productsList;  
                                    printf("Guessed product (%p): score=%d product=%s file_name=%s\n", pProduct, pProduct->score, pProduct->product, pProduct->file_name);  
                                    zway_device_guess_free(productsList);  
                               }  
                               pDeviceNodeId++;  
                          }  
                          zway_devices_list_free(devicesList);  
                     } else {  
                          printf("No devices?\n");  
                     }  
                }  
                printf("Stopping ZWay...\n");  
                result = zway_stop(theZWay);  
           }  
      }  
      if (result != NoError) {  
           printf("Error: %d\n", result);  
      }  
      zway_terminate(&theZWay);  
      return 0;  
 }  

Now the following step for me is to understand how to write callbacks to get notified when a Z-Wave event occurs.
