[james28909]: here is a question, that hopefully i wont be made fun of for asking, but what exactly is a dereference?
[james28909]: isnt that like breaking some kind of link between something...
[james28909]: in google it says dereference means "obtain from (a pointer) the address of a data item held in another location."
[shmem]: dereferencing is getting the thing a reference points to.
[james28909]: but to me that sounds like it is actually referencing that data instead of dereferencing it. to me dereference means to break some kind of link or something
[james28909]: the dereference is the physical address of the data needed referenced?
