It is an image viewer that I wrote in pure C language.
I would like to be able to include 8bf files.
How could I do it?

Yes, I am new
I have downloaded these plugins as an example.

I must have misunderstood your request
8BF is not a graphics file format, just a plugin format for Photoshop. I was originally under the impression you'd like to add that file-type to your forum-post, but it can also be read as if you want to add support for displaying these files to your application, so that's not going to work.
For adding the feature of using such plugins to your application I can only point you to the
Adobe developer community, they know how to guide you in that direction.
