atexit(3) and on_exit(3) calls either exit () or longjmp(3). Note that a call to execve(2) removes registrations created using atexit(3) and on_exit(3). The use of EXIT_SUCCESS and EXIT_FAILURE is slightly more portable (to non-UNIX environments) than the use of 0 and some nonzero value like 1 or -1. In particular, VMS uses a different
