Hi
I need to read approximately 10 bytes out from a 1.6 gig file on the hard drive. This needs to be done very frequently and so it has to be quick. I understand that using Interrupts is slower than writing your own read routine. However I haven't found any examples on the net of a non-interrupt IO routine. Does anyone know of anything that may be useful?
Many thanks in advance
