                      2:  * libc/stdio/exit.c
                      3:  * C general utilities library.
                      4:  * exit()
                      5:  * ANSI 4.10.4.3.
                      6:  * Normal termination.
                      7:  * Implementation defined behavior:
                      8:  *     successful termination (status==0 or status==EXIT_SUCCESS) returns 0
                      9:  *     unsuccessful termination (status==EXIT_FAILURE) returns 1
                     10:  *     otherwise (status!=EXIT_SUCCESS && status!=EXIT_FAILURE) returns status
                     11:  * This just passes the given status to the system,
                     12:  * which works since EXIT_SUCCESS is 0 and EXIT_FAILURE is 1.
                     13:  * Should be in libc/stdlib/exit.c but is in libc/stdio/exit.c instead
                     14:  * because the order of objects in the library is significant,
                     15:  * cf. libc/stdio/Makefile.
