Function decodeUpto65535

src/simplicity/bitstream.c:171–177

Decode an encoded number between 1 and 65535 inclusive. * When successful returns the decoded result. * If the decoded value would be too large, 'SIMPLICITY_ERR_DATA_OUT_OF_RANGE' is returned. * If more bits are needed than available in the 'stream', 'SIMPLICITY_ERR_BITSTRING_EOF' is returned. * If an I/O error occurs when reading from the 'stream', 'SIMPLICITY_ERR_BISTRING_ERROR' is returned.

 * Precondition: NULL != stream
