From: Elia Pinto Date: Mon, 21 Mar 2022 22:54:51 GMT Subject: [PATCH 09/41] mailsplit.c: use the stdlib EXIT_SUCCESS or EXIT_FAILURE exit status Message-ID: <20220321225523.724509-10-gitter.spiros@gmail.com> In-Reply-To: <20220321225523.724509-1-gitter.spiros@gmail.com> The C standard specifies two constants, EXIT_SUCCESS and EXIT_FAILURE, that may be passed to exit() to indicate successful or unsuccessful termination, respectively. The value of status in exit(status) may be EXIT_SUCCESS, EXIT_FAILURE, or any other value, though only the least significant 8 bits (that is, status & 0377) shall be available to a waiting parent proces. So exit(-1) return 255. Use the C standard EXIT_SUCCESS and EXIT_FAILURE to indicate the program exit status instead of "0" or "1", respectively. In EXIT_FAILURE has the value "1": use EXIT_FAILURE even if the program uses exit(-1), ie 255, for consistency.
