NAME
       exit, atexit - terminate a process after flushing any pending output

SYNOPSIS
       #include <stdlib.h>

       void exit(int status)
       int atexit(void (*func)(void))

DESCRIPTION
       Exit  first  calls  all	functions  registered by atexit, flushes all data buffered by the Standard I/O library, and finally terminates the
       process.  Exit never returns.

       Atexit registers the function func into a table of functions to be called on exit.

DIAGNOSTICS
       Atexit returns 0 on success, -1 if malloc cannot allocate more memory for the list of registered functions.
