ExitProcess function (processthreadsapi.h)

Ends the calling process and all its threads.

void ExitProcess(
  [in] UINT uExitCode
);

[in] uExitCode

The exit code for the process and all threads.

None

Use the GetExitCodeProcess function to retrieve the process's exit value. Use the GetExitCodeThread function to retrieve a thread's exit value.

Exiting a process causes the following:

1. All of the threads in the process, except the calling thread, terminate their execution without receiving a DLL_THREAD_DETACH notification.
2. The states of all of the threads terminated in step 1 become signaled.
3. The entry-point functions of all loaded dynamic-link libraries (DLLs) are called with DLL_PROCESS_DETACH.
4. After all attached DLLs have executed any process termination code, the ExitProcess function terminates the current process, including the calling thread.
5. The state of the calling thread becomes signaled.
6. All of the object handles opened by the process are closed.
7. The termination status of the process changes from STILL_ACTIVE to the exit value of the process.
8. The state of the process object becomes signaled, satisfying any threads that had been waiting for the process to terminate.

Calling ExitProcess in a DLL can lead to unexpected application or system errors. Be sure to call ExitProcess from a DLL only if you know which applications or system components will load the DLL and that it is safe to call ExitProcess in this context.

Exiting a process does not cause child processes to be terminated.

Exiting a process does not necessarily remove the process object from the operating system. A process object is deleted when the last handle to the process is closed.

For an example, see Creating a Child Process with Redirected Input and Output.
