You can write a Pascal unit that will have the API and read it from the library.
Thats might be a lot of work (usually if h2pas does not work well :( ), but it
will give you native support.

A short note, an environment variables are not very safe to use, because anyone
can change them to whatever they wishes.
Regardless of that, try to use either pipe to an output. There are other ways
such as signals that can help you, but as I wrote above, the best way, alto it
will take a lot of work, will be to create a unit that will read the functions
from the library and will give you the native use with it in Pascal.
