Reloading a shared c library after been modified?

hi all,
i've made a simple shared c library for learning purposes
that i call using nativeboost. Now the problem i'm facing
it's that after i changed the library i have to close and
open the image to get those changes, so the question
is there a way to update the library loaded in the image without
closing and opening the image?

thanks.

Hello,

this is possible but non trivial.

I think the easiest way is to bind the C functions to manage C libraries: dlopen, dlsym, dlclose, dlerror. Then you can manually open and close the dynamic libs (dlopen, dlclose) and call the function dynamically loaded with dlsym. dlerror is used for error handling (else you don't know why your call failed).

Clement.
