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 as follows:

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
