2000-02-06 Martin Baulig <martin@home-of-linux.org> * glibtop.h (glibtop): Removed `method', `server_command', `server_host', `server_user' and `server_rsh'. Added `glibtop_parameter _param' field and moved `error_method' there. * include/glibtop/parameter.h (glibtop_parameter): New structure. (GLIBTOP_PARAM_METHOD, GLIBTOP_PARAM_COMMAND): Removed. (GLIBTOP_PARAM_HOST, GLIBTOP_PARAM_PORT): Removed. (GLIBTOP_PARAM_REMOTE_USER, GLIBTOP_PARAM_PATH_RSH): Removed. (GLIBTOP_PARAM_NCPU, GLIBTOP_PARAM_OS_VERSION_CODE): Added.
