Background
I'm making an out-of-band API for working around a limitation of a layer between my plugin and my application.
The correct solution would be to update the middle layer to support the extra API, and that is in progress, but unfortunately that will take too long.
Question
I am using dlopen(NULL, RTLD_NOW) in the application to search for symbols in the plugin. Will that prevent my plugin library from being unloaded until a matching dlclose(NULL)?
I'm assuming not, but I can always hope.
Answer
Turns out that dlopen(NULL, RTLD_NOW) does not prevent my plugin from being unloaded. I'm going to look into something using dladdr to maybe work something out. I'll post it as an answer if I get time.
