What work at the OS level is being negated?

I will repeat my question. What are the functions that can be reused in 
Erlang but not in imperative languages?
Feel free to use Java instead of C in your examples.
It seems to me that it is completely equivalent. Every time you have an 
Erlang function, there is a corresponding Java function.

Functional languages should have larger libraries then, if these claims 
were true. But that doesn't seem to be the case.
