Lightbulb memory calculation

hi all,

sorry for silly question.
but i have a doubt in calculation of memory utilization calculation.

using 'free' command we calculate the memory utilization as
used/total.

but my friend said that its wrong and we have to include cached also as
(used-cached)/memory.

but these gives us much variation between our calculation and this. we totally in confusion about it.....

pleae help me out.


Tanks in advance.

The procedure is passed a pointer to an XColor structure representing the back- ground color. The pixel, red, green, and blue members of this structure are filled in with values that are valid for the current colormap. The procedure is passed pointers to XColor structures representing the foreground, select, top shadow, and bottom shadow colors to be cal- culated. The procedure calculates and fills in the red, green, and blue members of these structures. The procedure should not allocate color cells for any of these colors. Specifies the background color.
