#24168 — What does "Exited with code: 1" mean?

Searching the web I see this mentioned a lot but no underlying cause.

 From console:

2012-04-21 1:51:31.598 PM com.apple.launchd.peruser.501: 
([0x0-0x36e36e].com.Google.GoogleEarthPlus[9877]) Exited with code: 1

(The app started with no issue immediately afterwards).

In *nix (Which, being a BSD-variant, is effectively what MacOS X is) an 
exit code of "any value other than 0" from a program is a pretty generic 
indication of some sort of error.

What kind of error? Take your best guess. Maybe you were holding your 
mouth wrong when you fired up the program. Maybe a file it needs is 
locked, missing, corrupted, or inaccessible. Maybe the martians have 
landed. Maybe something took too long to respond. Maybe SkyNet has 
become sentient and the nukes have been launched. Maybe (fill in your 
own "maybe")

Aside from the widely-used (but by no means universally observed) *nix 
convention that an exit code of 0 means "Program ended normally", 
there's no standardization - A programmer is free to return whatever 
exit code (or none at all...) (s)he likes when the program shuts down. 
Unless you're the programmer, or a code-to-meaning translation for the 
exact program in question is available, the precise meaning of any 
non-zero exit code you might see from a program is anybody's guess.
