chapter192, [SORA] About Blockchain mini filesystem structure, part3

We have finished testing fs_disk. We are able to confirm that there was no problem by reading the randomly written information and comparing. This is code below.

for(index_t test=0; test < 64; ++test) {
        const sector_t begin = rand() % 10000000;
        const counter_t num = rand() % 94581920;
        if(num==0) continue;
        const fsize_t bsize = num * SECTOR_SIZE;
        byte_t *wbuf = fs_malloc(bsize);
        assert(wbuf);
        {
               FSDISK *fdp;
               assert(fs_disk_open(&fdp));
               for(index_t i = 0; i < bsize; ++i)
                      wbuf[i] = (byte_t)rand();
               assert(fs_disk_write(fdp, begin, num, wbuf));
               fs_disk_close(fdp, true_t);
        }
        {
               FSDISK *fdp;
               assert(fs_disk_open(&fdp));
               byte_t *rbuf = fs_malloc(bsize);
               assert(rbuf);
               assert(fs_disk_read(fdp, begin, num, rbuf));
               assert(memcmp(wbuf, rbuf, bsize) == 0);
               fs_free(rbuf, fs_disk_close(fdp, true_t));
        }
        fs_free(wbuf, true_t);
}
