So if you have thirty chats open, and want to hide them all, you will have to hide them one. From the navigation bar on the very left, select Chat. This will open all your chats with the contacts showing on the left, and the irritating open chat box on the right. (Ensure at top that Recent, not Contacts, is selected).
- I have a problem with the Gradle daemon not showing println output from my plugin on subsequent runs. I can workaround this problem by adding -no-daemon when I run from the command line. When I run the Gradle task from IDEA though, when I add -no-daemon to the 'script parameters' (not the 'VM options'), the execution fails with.
- 2) What is the Microsoft Database Daemon? The Microsoft Database Daemon allows the Reminder to work even if all MS applications are closed. The daemon is actually used all the time to access the Database. Even Word uses it. This is why you need to Quit Notifications and/or the Microsoft Database daemon when you install MS updates.
A daemon process is a process which runs in background and has no controlling terminal.
Since a daemon process usually has no controlling terminal so almost no user interaction is required. Daemon processes are used to provide services that can well be done in background without any user interaction.
For example a process that runs in background and observes network activity and logs any suspicious communication can be developed as a daemon process.
Daemon Process Design
A daemon process can be developed just like any other process but there is one thing that differentiates it with any other normal process ie having no controlling terminal. This is a major design aspect in creating a daemon process. This can be achieved by :
- Create a normal process (Parent process)
- Create a child process from within the above parent process
- The process hierarchy at this stage looks like : TERMINAL -> PARENT PROCESS -> CHILD PROCESS
- Terminate the the parent process.
- The child process now becomes orphan and is taken over by the init process.
- Call setsid() function to run the process in new session and have a new group.
- After the above step we can say that now this process becomes a daemon process without having a controlling terminal.
- Change the working directory of the daemon process to root and close stdin, stdout and stderr file descriptors.
- Let the main logic of daemon process run.
So we see that above steps mark basic design steps for creating a daemon.
C fork() Function
Before creating an actual running daemon following the above stated design steps, lets first learn a bit about the fork() system call.
fork() system creates a child process that is exact replica of the parent process. This new process is referred as ‘child’ process.
This system call gets called once (in parent process) but returns twice (once in parent and second time in child). Note that after the fork() system call, whether the parent will run first or the child is non-deterministic. It purely depends on the context switch mechanism. This call returns zero in child while returns PID of child process in the parent process.
Following are some important aspects of this call :
- The child has its own unique process ID, and this PID does not match the ID of any existing process group.
- The child’s parent process ID is the same as the parent’s process ID.
- The child does not inherit its parent’s memory locks.
- Process resource utilization and CPU time counters are reset to zero in the child.
- The child’s set of pending signals is initially empty.
- The child does not inherit semaphore adjustments from its parent.
- The child does not inherit record locks from its parent.
- The child does not inherit timers from its parent.
- The child does not inherit outstanding asynchronous I/O operations from its parent, nor does it inherit any asynchronous I/O contexts from its parent.

The Implementation
Based on the design as mentioned in the first section. Here is the complete implementation :

Following is the way through which the code was compiled and executed:
Just observe that the control immediately came back to the terminal ie the daemon is now not associated to any terminal.
When you check the log.txt file located in the root directory, you could see that this daemon process is running.
