2000-01-23 Martin Baulig <martin@home-of-linux.org> This is now a LibGTop backend which can be loaded additionally to the normal Linux sysdeps code. * open.c, close.c: Removed. * shm_limits.c, msg_limits.c, sem_limits.c, ppp.c: Removed. * siglist.c, sysinfo.c: Removed. * backend-kernel.c: New file. * glibtop-backend-private.h: New file. * libgtop-kernel.backend: New file. * backend-kernel.pl: New file. Automatically creates `backend-kernel.h'. * marshal.pl: New file. Automatically creates `marshal.c'. * glibtop_server.h: Replaced all `GLIBTOP_SUID_<feature>' constants with `GLIBTOP_IMPL_<feature>' ones; they're used in marshal.c to find out which features this backend implements. * *.c: Renamed all `glibtop_get_<feature>_s' functions to `glibtop_get_<feature>_k' and all `glibtop_init_<feature>_s' ones to `glibtop_init_<feature>_k'.
