Misleading indentation, please add two tabs to the second line of 
printf() statement.

Please don't break up strings to multiple lines.

I wish there was a middle ground between no indentation and way too much 
indentation...

Same as above, don't break up strings.

Same as above, two tabs is enough indentation.

Here and below:

I don't think saying *why* it should not be NULL - just saying that it 
shouldn't be NULL is enough. Maybe mention why it's supposed to be not 
NULL in comments here.

Also, i have a suspicion that the message is wrong - why would status be 
null if the environment was initialized? Presumably it's the other way 
around?
