Perform cleanup operations and return without terminating the process.
#include <process.h>
void _cexit( void );
void _c_exit( void );
The _cexit function calls, in LIFO (“last in, first out”) order, the functions registered by atexit and _onexit. Then the _cexit function flushes all I/O buffers and closes all open streams before returning.
The _c_exit function is the same as the _exit function but returns to the calling process without processing atexit or _onexit or flushing stream buffers.
The behavior of the exit, _exit, _cexit, and _c_exit functions is described in the following list:
| Function | Action |
| exit | Performs complete C library termination procedures, terminates the process, and exits with the supplied status code |
| _exit | Performs “quick” C library termination procedures, terminates the process, and exits with the supplied status code |
| _cexit | Performs complete C library termination procedures and returns to caller, but does not terminate the process |
| _c_exit | Performs “quick” C library termination procedures and returns to caller, but does not terminate the process |
