uuid

centos挂载硬盘 挂载硬盘步骤: 1. 先分区 fdisk /dev/sdb -p 查看分区 -n 创建分区 -p 创建主分区 -1 这是分区序号 -回车，回车（这里选择扇区起始位置和分区大小，类似：+1G 这样的格式） -w 保存退出 2. 格式化 mkfs.ext4 /dev/sdb1 3. 挂载 比如挂载到 /data0下面，则先创建目录 mkdir /data0 再挂载： mount /dev/sdb1 /data0 4. 硬盘随机启动挂载 vim /etc/fstab里面添加如下内容： /dev/sdb1 /data2 ext4 defaults 0 0 或者 UUID=a4a6201b-4e1e-4f64-bde0-dc502599be2e /data2 ext4 defaults 0 0 更推荐下面这种方式，查看UUID通过命令：blkid 查看，例如： [root@hadooptest ~]# blkid /dev/sda1: UUID="313f8b93-ed62-4f3f-9b27-d92d844fbb6e"TYPE="swap" /dev/sda2: UUID="56adf238-c8b2-4458-882b-bfa7204042de"TYPE="ext4" /dev/sdb1: UUID="2fd1b7ca-d4de-4a40-b1e5

I received help from someone here a week or so ago, but there seems to still be a problem with my code. I am running Android 2.0 so I cannot use the methods to get the UI, instead I need to call the methods reflectively. Below is my code public ConnectThread(BluetoothDevice device, boolean secure) { Log.d(TAG,"here5"); mmDevice = device; BluetoothSocket tmp = null; mSocketType = secure ? "Secure" : "Insecure"; Log.d(TAG,"here6"); // Get a BluetoothSocket for a connection with the // given BluetoothDevice ParcelUuid[] uuids = servicesFromDevice( mmDevice ); Log.d( Integer.toString( uuids.length

I need to know UUID on API 8 (2.2) or possibly 2.3.3. As I understand the documentation, this should be allowed: phoneDevice = blueAdapter.getRemoteDevice(phoneAddress); ParcelUuid[] phoneUuids = phoneDevice.getUuids(); // Won't compile Eclipse gives me: "The method getUuids() is undefined for the type BluetoothDevice." But see: http://developer.android.com/reference/android/bluetooth/BluetoothDevice.html#getUuids () Also, I would like to know how the UUIDs are "parceled" inside the ParcelUuid[]. In case I ever manage to get there, how do I retrieve a UUID from a parcelUuid[]? Documentation

I was looking at libblkid and was confused about the documentation. Could someone provide me with an example of how I could find the UUID of a root linux partition using this library? It's pretty much as simple as the manual makes it look: you create a probe structure, initialize it, ask it for some information, and then free it. And you can combine the first two steps into one. This is a working program: #include <stdio.h> #include <stdlib.h> #include <err.h> #include <blkid/blkid.h> int main (int argc, char *argv[]) { blkid_probe pr; const char *uuid; if (argc != 2) { fprintf(stderr, "Usage:

Is there a reverse or inverse of the id built-in function? I was thinking of using it to encode and decode string without taking too much time or having a lot of overhead like the PyCrypto library. The need for me is quite simple so I don't want to use PyCrypto for a simple encode and decode. Something like: >>> id("foobar") 4330174256 >>> reverse_id(4330174256) # some function like this to reverse.
