The closest text I found so far is from IEEE Std 1003.1™-2024 XCU 1.4 Utility Description Defaults CONSEQUENCES OF ERRORS 79953 • When an unrecoverable error condition is encountered, the utility shall exit with 79954 an exit status that indicates an error occurred. 79955 • A diagnostic message shall be written to standard error whenever an error 79956 condition occurs. (the numbers are the total line numbers from the pdf instance of the standard).
