glibtop_get_uptime ()

void
glibtop_get_uptime (glibtop_uptime *buf);

When porting LibGTop to a new system, you only need to implement uptime and idletime if there's a faster or better way to obtain them as using function(glibtop_cpu) for it. Look at sysdeps/freebsd/uptime.c for an example on how to obtain them using function(glibtop_cpu).
