 Seems to be slightly more complex.
 
 read_cd_capacity(struct scsipi_periph *periph, u_int *blksize, u_long *size)
 error = read_cd_capacity(cd->sc_periph, &blksize, &size);
 error = read_cd_capacity(cd->sc_periph, &blksize, &size);
 error = read_cd_capacity(periph, &mmc_discinfo->sector_size, &last_lba);
 
 One time the caller apparently expects the last_lba value as is returned
 by the READ RECORDED CD CAPACITY command.
