## Discussion

Discussion The C programming language defines two standard exit codes, EXIT_SUCCESS and EXIT_FAILURE. Platforms may additionally define their own non-standard exit codes:  |   |   |   |   |   |  On macOS, FreeBSD, OpenBSD, and Windows, the full exit code reported by the process is reported to the parent process. Linux and other POSIX-like systems may only reliably report the low unsigned 8 bits (0–255) of the exit code.
