  Reads a number of sectors (AKA blocks).

  this location is large enough. See below for size information.

  If read_mode is CDIO_MODE_AUDIO,
    *p_buf should hold at least CDIO_FRAMESIZE_RAW * i_blocks bytes.

  If read_mode is CDIO_MODE_DATA,
    *p_buf should hold at least i_blocks times either ISO_BLOCKSIZE, 
    M1RAW_SECTOR_SIZE or M2F2_SECTOR_SIZE depending on the kind of 
    sector getting read. If you don't know whether you have a Mode 1/2, 
    Form 1/ Form 2/Formless sector best to reserve space for the maximum
    which is M2RAW_SECTOR_SIZE.

  If read_mode is CDIO_MODE_M2F1,
    *p_buf should hold at least M2RAW_SECTOR_SIZE * i_blocks bytes.

  If read_mode is CDIO_MODE_M2F2,
    *p_buf should hold at least CDIO_CD_FRAMESIZE * i_blocks bytes.
