_cexit, _c_exit

 

The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The latest version of this topic can be found at _cexit, _c_exit.

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 does not terminate process.
_c_exit Performs quick C library termination procedures and returns to caller, but does not 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 are not called. An automatic object is an object that is defined in a function where the object is not 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( );  

Requirements
