Looking for a way to flush writes to the raw disk or volume devices.
This is the code I'm looking at in gptfdisk's diskio-unix.cc:
#if defined (__FreeBSD__) || defined (__FreeBSD_kernel__)
sleep(2);
i = ioctl(fd, DIOCGFLUSH);
cout << "Warning: The kernel may continue to use old or deleted
partitions.\n"
<< "You should reboot or remove the drive.\n";
platformFound++;
#endif
I'm not seeing any equivalent to DIOCGFLUSH in the openbsd headers.
grep FLUSH /usr/include/sys/* seems to mostly turn up tty stuff.
