The example shows how to:
  1. Specify name of the data file and properties the dataset should be initialised with.

    	const char* fileName = argv[1];
    	const char* properties = "IsMobile";
    	

  2. Instantiate the 51Degrees provider from the specified data file with the required properties, number of worksets in the pool and cache of the specific size.

    	fiftyoneDegreesInitProviderWithPropertyString(
    	fileName, &provider, properties, 4, 1000);
    	

  3. Retrieve a workset from the pool and use it for a single match.

    	fiftyoneDegreesWorkset *ws = NULL;
    	ws = fiftyoneDegreesProviderWorksetGet(&provider);
    	

  4. Obtain match method: provides information about the algorithm that was used to perform detection for a particular User-Agent. For more information on what each method means please see: How device detection works

    ws->method

  5. Obtain difference: used when detection method is not Exact or None. This is an integer value and the larger the value the less confident the detector is in this result.

    	ws->difference

  6. Obtain signature rank: an integer value that indicates how popular the device is. The lower the rank the more popular the signature.

    	fiftyoneDegreesGetSignatureRank();
    	

  7. Release the workset back into the pool of worksets to be reused in one of the next matches.

    	fiftyoneDegreesWorksetRelease(ws);
    	

  8. Finally release the memory taken by the provider.

    	fiftyoneDegreesProviderFree(&provider);
    	

This example assumes you have compiled with 51Degrees.c and city.c. This will happen automatically if you are compiling as part of the Visual Studio solution. Additionally, when running the program, the location of a 51Degrees data file must be passed as a command line argument if you wish to use Premium or Enterprise data files.
