A big project is coming.  It is said that it take us about two months.  As a matter of fact, I ordered a meeting room for three days to explainthe project.  Three days!  My god!  The first time, I meet a project that need three days to be explaint.  What scale is this project?  To be continued.  setpgid() sets the process group ID of the process specified by  pid  to  pgid.  If pid is zero, the process ID of the current process is used.  If pgid is zero,the process ID of the process specified by pid is used.  If setpgid is used to move a process from one process group to another (as is done by some shells when creatingpipelines), both process groups must be part of the same session.  In this case, the pgid specifies an existing process group to be joined and the session ID of thatgroup must match the session ID of the joining process.
