2000-01-12 Martin Baulig <martin@home-of-linux.org> * include/glibtop/backend.h (glibtop_backend_entry): New type. (glibtop_backend_module): New private type. * lib/backend.c (glibtop_register_backend): This now takes a `glibtop_backend_entry' argument, not a `glibtop_backend_info' one. (glibtop_backend_by_id): Return a `glibtop_backend_entry' type, not a `glibtop_backend_info' one. (glibtop_backend_by_name): Likewise. * lib/init-backends.c: If we have libxml, read all `.backend' files in $(LIBGTOP_BACKEND_DIR), XML parse them and register them via `glibtop_backend_register'. This builds a list of all currently supported backends without actually loading them into memory. * lib/open-backend.c (glibtop_open_backend_l): GModule load the backend if it's not already in memory.
