manbetx手机网页版成立属于其它Session的进度

 
创造其余Session(User)的长河须要获得相应Session的Token作为CreateProcessAsUser的参数来启动进度。 

Sessions:A session is a collection of one or more process groups.

 
修改有System权限的Token的TokenId为其余Session的TokenId就足以在其余Session里面创立有System权限的进程了。

Sessions:是单个或多少个经过组的一个成团。

process establishes a new session by calling the setsid function.
进程靠调用setsid()创造一个会话。
#include <unistd.h>
pid_t setsid(void);

If the calling process is not a process group leader, this function
creates a new session. Three things happen
假若调用进程不是首席执行官进程,函数setsid()会创立一个新的对话。起到多个职能:
  1.The process becomes the session leader of this new session. (A
session leader is the process that creates a session.) 
     调用经过成为新会话的the session
leader。A session leader 是创立会话的进程。
     The process is the only process in this new session.
     在新的对话中,调用进度是绝无仅有的历程。
  2.The process becomes the process group leader of a new process group.
The new process group ID is the process ID of the calling process.
     调用经过成为新进度组的老董进度。新进度组ID就是调用进程的经过ID。
  3.The process has no controlling terminal. (We’ll discuss controlling
terminals in the next section.)   
     调用经过没有控制终端。
     If the process had a controlling terminal before calling setsid,
that association is broken.
     在调用setsid()此前,若是调用进度有决定终端,
那么调用进度会脱离这些决定终端。

 

This function returns an error if the caller is already a process group
leader. 

借使调用进度一度是一个首席执行官进度,则函数再次回到出错。
To ensure this is not the case, the usual practice is to call fork and
have the parent terminate and the child continue.
为了幸免那种情景发生,日常的做法是调用fork()使父进程终止,子进度继续运行。
We are guaranteed that the child is not a process group leader, because
the process group ID of the parent is inherited by the child,
咱俩保险了子进程不是高管进度,因为父进程的进度组ID没有被子进度继续,
but the child gets a new process ID. Hence, it is impossible for the
child’s process ID to equal its inherited process group ID.
而子进程取得一个新进程ID。由此,子进度ID等于它接二连三的进度组ID是不可能的。
