This function ends a process and all of its threads.
VOID ExitProcess( UINT uExitCode );
[in] Specifies the exit code for the process and for all threads that are terminated as a result of this call.
To retrieve the process's exit value, use the GetExitCodeProcess function.
To retrieve a thread's exit value, use the GetExitCodeThread function.
This function is the preferred method of ending a process because it provides a clean process shutdown. This includes calling the entry-point function of all attached DLLs with a value indicating that the process is detaching from the DLL.
After all attached DLLs have executed a process termination value, this function terminates the current process.
The following actions are caused by terminating a process:
- All object handles that were opened by the process are closed.
- All threads in the process terminate their execution.
- The state of the process object becomes signaled, satisfying threads waiting for the process to terminate.
- The states of all threads of the process become signaled, satisfying threads waiting for the threads to terminate.
- The termination status of the process changes from STILL_ACTIVE to the exit value of the process.
Terminating a process does not necessarily remove the process object from the OS. A process object is deleted when the last handle to the process is closed.
A process that is started as a result of a call by CreateProcess is run serially with the ExitProcess, ExitThread, and CreateThread functions. Within the parent process, only one of these events can happen in an address space at a time.
The following list shows the restrictions during the process:
- During process startup and DLL initialization routines, new threads can be created, but they do not begin execution until DLL initialization is done for the process.
- In a process, only one thread at a time can be in a DLL initialization or detach routine.
- ExitProcess does not return to processes in the DLL initialization or detach routine.
