I am trying to make sense of the argument of pushing configuration into a library: * if the library is just a dependency, the Linux loader will set it up.

I am trying to make sense of the argument of pushing configuration into a library: * if the library is just a dependency, the Linux loader will set it up. It will have the same environment as the other libraries and as the main program. * if the library is set up by dlopen(), there is no way to provide an environment pointer Altering the global environment variable for child processes makes no sense, for execve() accepts an char* envp[] . So I guess we need to talk about issues with a specific use case of dlopen()
