How to check if OleInitialize has already been called?

Question

I want to write a Delphi function to register a dll. I want the function to check if OleInitialize has already been called before it does it. I guess I'm trying to avoid the consequences of initialization twice, because I'm not sure what they can be. I am worried that my function will not process many different DLLs like regsvr32.exe.

Take a look at the documentation :

Return Value
[...]
S_FALSE- The COM library is already initialized in this apartment.

... and:

COM . , concurrency, S_FALSE.
