Package dlopen provides some convenience functions to dlopen a library and get its symbols. In the above example, if you provide the field values of Library, Magazines, and Health, then you get the desired occurrence of the Health segment. */ 44: const void *caller; 45}; 46: 47: 48 /* Non-shared code has no support for multiple namespaces. Use dlopen() with that file descriptor to load the new code; Profit; Of course this approach is pretty “lazy”, but still being a valid trick to use in our operations.
