On Windows use MemoryModule, on Linux just dlopen the file or socket.

argv[0] should be the symbol name to load and call.

Then call the symbol with:

symbol(socket_handle, argc, argv);

This is what I was looking for when I came here. I'm trying to find a library that will take an ELF string with a single function defined in it and produce a function pointer that I can call.

You could use dlopen in combination with memfd and /process/self/fd/...

Use pwnlib to generate the elf file.

It should be easy to implement the dlopen functionality in netelf, but I wanted to keep the code simple.
