Pass the O_SYNC flag to open(). This will cause write() calls to block until the data has been sent to the drive. The O_DIRECT flag suggested by Steve is probably overkill. It requires that the buffer start address, buffer size and file offset are all multiples of the filesystem's block size, and only works on some filesystems. -- Glynn Clements <glynn@xxxxxxxxxxxxxxxxxx> - : send the line "unsubscribe linux-c-programming" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
