+// Package winquit supports graceful shutdown of Windows applications through
+// the sending and receiving of Windows quit events on Win32 message queues.
+// This allows golang applications to implement behavior comparable to SIGTERM
+// signal handling on UNIX derived systems. Additionally, it supports the
+// graceful shutdown mechanism employed by Windows system tools, such as
+// taskkill. See the "How it works" section for more details.
+//
+// To aid application portability, and provide familiarity, the API follows a
+// similar convention and approach as the os.signal package. Additionally, the
+// SimulateSigTermOnQuit function supports reuse of the same underlying channel,
+// supporting the blending of os.signal and winquit together (a subset of
+// signals provided by os.signal are still relevant and desirable on Windows,
+// for example, break handling in console applications).
+//
+// # Simple server example
+//
+// The following example demonstrates usage of NotifyOnQuit() to wait for a
+// windows quit event before shutting down:
+//
+//	func server() {
+//	    fmt.Println("Starting server")
+//
+//	    // Create a channel, and register it
+//	    done := make(chan bool, 1)
+//	    winquit.NotifyOnQuit(done)
+//
+//	    // Wait until we receive a quit event
+//	    <-done
+//
+//	    fmt.Println("Shutting down")
+//	    // Perform cleanup tasks
+//	}
+//
+// # Blended signal example
+//
+// The following example demonstrates usage of SimulateSigTermOnQuit() in
+// concert with signal.Notify():
+//
+//	func server() {
+//	    fmt.Println("Starting server")
+//
+//	    // Create a channel, and register it
+//	    done := make(chan os.Signal, 1)
+//
+//	    // Wait on console interrupt events
+//	    signal.Notify(done, syscall.SIGINT)
+//
+//	    // Simulate SIGTERM when a quit occurs
+//	    winquit.SimulateSigTermOnQuit(done)
+//
+//	    // Wait until we receive a signal or quit event
+//	    <-done
+//
+//	    fmt.Println("Shutting down")
+//	    // Perform cleanup tasks
+//	}
+//
+// # Client example
+//
+// The following example demonstrates how an application can ask or
+// force other windows programs to quit:
+//
+//	func client() {
+//	     // Ask nicely for program "one" to quit. This request may not
+//	     // be honored if its a console application, or if the program
+//	     // is hung
+//	     if err := winquit.RequestQuit(pidOne); err != nil {
+//	         fmt.Printf("error sending quit request, %s", err.Error())
+//	     }
+//
+//	     // Force program "two" to quit, but give it 20 seconds to
+//	     // perform any cleanup tasks and quit on it's own
+//	     timeout := time.Second * 20
+//	     if err := winquit.QuitProcess(pidTwo, timeout); err != nil {
+//	         fmt.Printf("error killing process, %s", err.Error())
+//	     }
+//	}
+//
+// # How it works
+//
+// Windows GUI applications consist of multiple components (and windows) which
+// intercommunicate with events over per-thread message queues and/or direct
+// event handoff to window procedures for cross-thread communication.
+// Additionally, GUI applications can use the same mechanism to communicate with
+// windows and threads owned by other applications, including common desktop
+// components.
+//
+// winquit utilizes this mechanism by creating a standard win32 message loop
+// thread and registering a non-visible window to relay a quit message (WM_QUIT)
+// in the event of a window close event. WM_CLOSE is sent by Windows in response
+// to certain system events, or by other requesting applications. For example,
+// the system provided taskkill.exe (similar to the kill command on Unix), works
+// by iterating all windows on the system, and sending a WM_CLOSE when the
+// process owner matches the specified pid. Note that, unlike UNIX/X11 style
+// systems, on Windows the graphical APIs are built-in and accessible to all
+// win32 applications, including console based applications. Therefore, the APIs
+// provided by winquit *do not* require compilation as a windowsgui app to
+// effectively use them.
+//
+// winquit also provides APIs to trigger a quit of another process using a
+// WM_CLOSE event, although in a more efficient manner than taskkill.exe. It
+// instead captures a thread snapshot of the target process (effectively a
+// memory read on Windows), and enumerates each thread's associated Windows, and
+// sending the event to each. In addition to supporting a graceful close of any
+// Windows application, which may have multiple message loops, this approach
+// also obviates the need for cumbersome approaches to lock code to the main
+// thread of the application. The message loop used by winquit does not care
+// which thread the golang runtime internally designates. Note that winquit
+// purposefully relays through a thread's windows as opposed to posting directly
+// to each thread's message queue, since the former is more likely to be
+// expected by an application, and it ensures all window procedures have an
+// opportunity to perform cleanup work not associated with the thread's message
+// loop.
+//
+// # Limitations
+//
+// This API is only implemented on Windows platforms. Non-operational stubs
+// are provided for compilation purposes.
+//
+// In addition to requiring appropriate security permissions (typically a user
+// can only send events to other applications ran by the same user), Windows
+// also restricts inter-app messaging operations to programs running in the same
+// user logon session. While logons migrate between RDP and console sessions,
+// non-graphical logins (e.g sshd) typically create a logon per connection. For
+// this reason, tools like taskkill and winquit are normally disallowed from
+// crossing this boundary. Therefore, a user will not be able to gracefully stop
+// applications between ssh/winrm sessions, and in between ssh and graphical
+// logons. However, the typical user use-case of logging into Windows and
+// running multiple applications and terminals will work fine. Additionally,
+// multiple back-grounded processes in the same ssh session will be able to
+// communicate. Finally, it's possible to bypass this limitation by executing
+// code under the system user using the SeTcbPrivilege. The psexec tool does
+// exactly this, and can additionally be used as a workaround to this
+// limitation.
