It changes the return values of all sysdeps functions which were previosly returning void to int. This is the first step to implement better error handling in LibGTop. Martin 1999-10-24 Martin Baulig <martin@home-of-linux.org> * include/glibtop/*.h (glibtop_get_*, glibtop_init*): Changed the return value of all `glibtop_get_<feature>_* ()' and all `glibtop_init_<feature>_* ()' functions from void to int. * features.def: Reflect changes of the return values. * sysdeps/*/*.c: Reflect changes of the return values.
