CTRL+CLOSE Signal

The system generates a CTRL+CLOSE signal when the user closes a console. All processes attached to the console receive the signal, giving each process an opportunity to clean up before termination. When a process receives this signal, the handler function can take one of the following actions after performing any cleanup operations:

  • Call ExitProcess to terminate the process.
  • Return FALSE. If none of the registered handler functions returns TRUE, the default handler terminates the process.
  • Return TRUE. In this case, no other handler functions are called and the process terminates.
