glibtop_get_cpu ()

void                glibtop_get_cpu                     (glibtop_cpu *buf);

Get the CPU usage.

All CPU units are measured in jiffies which are normally 1/100th of a second (in which case frequency equals 100), but can also be in any other unit. To get seconds, divide them by frequency.

buf :

A location to return the CPU usage.
