This=A0means that addr points to a memory location where the string
stored is "0xae456778"

Yes, you can parse each individual character of the hex-format string
and convert it to its integral equivalent (you can find many samples
of this on internet...) and assing this value to a void * and then
return it back..

Hope that helps..
