if i want load it from memory,how can i do?

Are you coding a malicious software?

If not, I can't see a valid reason why you want to do that so much. An external ".so" won't kill anyone (not to mention it is very common).

Possibilities:
1.If you still want to load it from memory, then recreating the functions you need in your own application will work.

2.Keep the ".so" in your "executable" and then extracting and loading it during runtime.

3.Literally loading it from memory without accessing the disk or other device.

Sorry, I never tried option 3. Try asking some Linux experts or read some books to understand how it works and create by yourself the method to achieve the desired result (the best way).

Thank you for posting!
