How to define a FFI LIbrary using a file handle or actual binary code, and NOT a filename?

[Rogue Wave]

I have a weird situation, especially since I am not allowed to get into any details at all.

But I can not create a new file, nor access the file system.  I can change this one file.

So I am appending the compiled .so library to the end of a ruby file after an __END__.

I can access that binary as the DATA file handle.  So I can use that, or read from the

file handle and use that.  Is there any way to create the FFI Library using either of these?

Thanks

The fundamental problem is that dl_open only accepts a filename, not a handle.

The best answer I can find is here:

In short, you'll have to use mmap and do some wiring on your own.
