Troubleshooting DLL Driver Error
Driver functions will return a status code when they are called to
perform a certain task for the application. When a function returns a
code that is not zero, it means the function has failed to perform its
designated function. To troubleshoot the DLL driver error, you can
pass the error code to DRV_GetErrorMessage function to return the
error message. Or you can refer to the DLL Driver Error Codes
