Parameters

exitCode:
The exit code reported by the process.

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:

Platform	Header
macOS	Exit.3, Sysexits.3
Linux	Exit.3, Sysexits.h.3head
FreeBSD	Man.cgi?exit(3), Man.cgi?sysexits(3)
OpenBSD	Exit, Sysexits
Windows	Exit Success Exit Failure

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.
