Where did you find/download this "libcurl.dll"?

This is not only very ugly code (ugly because you attempt to use the plain
numbers instead of the prefered names for the options), it also won't work.
There are no options in libcurl that use the numbers 1 or 2. If you really
need to do it this way, you need to understand the CINIT() macro used in the
curl.h file, as it adds two numbers. One of them being the type of the option,
the other being the enumerated option number.

I would suggest writing a less crude interface.

It might not be. What are the requirements for it to be recognized as such?
