Performs cleanup operations and returns without terminating the process.
Syntax
void _cexit( void );
void _c_exit( void );
Remarks
The _cexit function calls, in last-in, first-out (LIFO) order, the functions registered by atexit and _onexit. Then _cexit flushes all I/O buffers and closes all open streams before returning. _c_exit is the same as _exit but returns to the calling process without processing atexit or _onexit or flushing stream buffers. The behavior of exit, _exit, _cexit, and _c_exit is shown in the following table.
| Function | Behavior |
|---|---|
exit |
Performs complete C library termination procedures, terminates process, and exits with supplied status code. |
_exit |
Performs quick C library termination procedures, terminates process, and exits with supplied status code. |
_cexit |
Performs complete C library termination procedures and returns to caller, but doesn't terminate process. |
_c_exit |
Performs quick C library termination procedures and returns to caller, but doesn't terminate process. |
When you call the _cexit or _c_exit functions, the destructors for any temporary or automatic objects that exist at the time of the call aren't called. An automatic object is an object that is defined in a function where the object isn't declared to be static. A temporary object is an object created by the compiler. To destroy an automatic object before calling _cexit or _c_exit, explicitly call the destructor for the object, as follows:
myObject.myClass::~myClass( );
By default, this function's global state is scoped to the application. To change this behavior, see Global state in the CRT.
