This is from test/libndctl.c in the ndctl repo:
fd = open(bdevpath, O_RDONLY);
if (fd < 0) {
fprintf(stderr, "%s: failed to open(%s, O_RDONLY)\n",
devname, bdevpath);
return -ENXIO;
}
...
ro = 0;
rc = ioctl(fd, BLKROSET, &ro);
if (rc < 0) {
fprintf(stderr, "%s: BLKROSET failed\n",
devname);
rc = -errno;
goto out;
}
close(fd);
fd = open(bdevpath, O_RDWR|O_DIRECT);
...
if (write(fd, buf, 4096) < 4096) {
fprintf(stderr, "%s: failed to write %s\n",
devname, bdevpath);
rc = -ENXIO;
goto out;
}
