The ExitProcess function ends a process and all its threads.
VOID ExitProcess( UINT uExitCode // exit code for all threads );
This function does not return a value.
ExitProcess is the preferred method of ending a process. This function provides a clean process shutdown. This includes calling the entry-point function of all attached dynamic-link libraries (DLLs) with a value indicating that the process is detaching from the DLL. If a process terminates by calling TerminateProcess, the DLLs that the process is attached to are not notified of the process termination.
After all attached DLLs have executed any process termination value, this function terminates the current process.
Terminating a process causes the following:
Terminating a process does not cause child processes to be terminated.
Terminating 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.
The ExitProcess, ExitThread, CreateThread, CreateRemoteThread functions, and a process that is starting (as the result of a call by CreateProcess) are serialized between each other within a process. Only one of these events can happen in an address space at a time. This means the following restrictions hold:
Windows NT: Requires version 3.1 or later.
Windows: Requires Windows 95 or later.
Windows CE: Unsupported.
Header: Declared in winbase.h.
Import Library: Use kernel32.lib.
