Ok. I see at least two different approaches to this.
1) provide checks for result values of functions
   may fail (my logic)
2) provide checks for function with no side effects

Which is better? This depends on your/my religion :-)
Your approach allows developer to remove useless/dead code.
This may be helpful too.

Ok. Do you see 100% candidates for "protection" from the list I sent?

write, read, fwrite, fread...?
I think there are _some_ that MUST be declared with WUR
and this list may be discussed.
