Problem: The extraction funcion always returns GR_NOT_ENOUGH_SPACE. What does that mean?

Solution: You must pass an already allocated byte array to the extraction function. If the array size is smaller than the resulting template size, the GR_NOT_ENOUGH_SPACE error code is returned. To avoid such situation, create such array with the size of GR_MAX_SIZE_TEMPLATE bytes.
