 ## Remarks  
  The `exit`, `_Exit` and `_exit` functions terminate the calling process. The `exit` function calls destructors for thread-local objects, then calls—in last-in-first-out (LIFO) order—the functions that are registered by `atexit` and `_onexit`, and then flushes all file buffers before it terminates the process. The `_Exit` and `_exit` functions terminate the process without destroying thread-local objects or processing `atexit` or `_onexit` functions, and without flushing stream buffers.  
 
- Although the `exit`, `_Exit` and `_exit` calls do not return a value, the low-order byte of `status` is made available to the host environment or waiting calling process, if one exists, after the process exits. Typically, the caller sets the `status` value to 0 to indicate a normal exit, or to some other value to indicate an error. The `status` value is available to the operating-system batch command `ERRORLEVEL` and is represented by one of two constants: `EXIT_SUCCESS`, which represents a value of 0, or `EXIT_FAILURE`, which represents a value of 1.

- When you call the `exit`,  `_Exit` or `_exit` function, the destructors for any temporary or automatic objects that exist at the time of the call are not called. An automatic object is defined in a function where the object is not declared to be static. A temporary object is an object that's created by the compiler. To destroy an automatic object before you call `exit`, `_Exit`, or `_exit`, explicitly call the destructor for the object, as follows:
