Use the bitwise and operator to determine each bit set in the bitmap that is returned by the permissions function 使用位与( & )运算符确定permissions函数返回的位图中的每个位集。
Clients should drop the connection if they receive bitfields that are not of the correct size , or if the bitfield has any of the spare bits set 如果本客户端收到一个长度错误的或是设置了多余的比特位的比特组，客户端应该断开连接。
On unix - like systems , shared directories need to have the sticky bit set . in sticky directories , files can be unlinked or renamed only by root or the file owner 在类unix系统上，需要设置共享目录的“ sticky ”位；在sticky目录中，文件只能由root或者文件的所有者解除链接或者重新命名。
You can broadcast to your local subnet by sending a packet to 255 . 255 . 255 . 255 ; or , you can use the directed broadcast address , which is the network portion of an internet protocol address with all bits set in the host portion 可以通过将数据包发送至255 . 255 . 255 . 255来广播到本地子网；或者，也可以使用定向广播地址，该地址为主机部分设置了所有位的internet协议( ip )地址的网络部分。
