2000-11-26 Martin Baulig <martin@home-of-linux.org> * backend-server.h: New file. (backend_server_private): New struct, formerly known as glibtop_backend_private. * glibtop-backend-private.h: Removed. * backend-server.c: (_open_server): Use g_object_set_data() to set add the backend_server_private data to the glibtop_backend, don't override `backend->_priv'. (_close_server): Use g_object_get_data() to get the data. [FIXME: Use quarks directly.] * read.c: (glibtop_read_i): Replaced the glibtop_server and glibtop_backend arguments with backend_server_private. * read_data.c: (glibtop_read_data_i): Likewise. * write.c: (glibtop_write_i): Likewise.
