This is a very big an possibly breaking commit.

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.
