  16 // The following requirements are tested:
  17 // (C.5.2)
  18 // The decvalue function decodes a bitstring into a value. The test system shall suppose that
  19 // the bitstring encoded_value represents an encoded instance of the actual type of decoded_value.
  20 // If the decoding was unsuccessful, the actual parameters for encoded_value and decoded_value are
  21 // not changed. The function shall return an integer value to indicate success or failure of the
  22 // decoding below:
  23 // The return value 2 indicates that decoding could not be completed as encoded_value did not
  24 // contain enough bits.
