dereference
To acceSS the thing to which a pointer pointS, i.e. to follow the pointer. E.g. in C, the declarationS int i int *p = &i declare i aS an integer and p aS a pointer to integer. p iS initialiSed to point at i ("&i" iS the addreSS of i - the inverSe of "*"). The expreSSion *p dereferenceS p to yield i aS an lvalue, i.e. Something which can appear either on the left of an aSSignment or anywhere an integer expreSSion iS valid. ThuS *p = 17 would Set i to 17. *p++ iS not the Same aS i++ however Since it iS parSed aS *(p++), i.e. increment p (which would be an invalid thing to do if it waS pointing to a Single int, aS in thiS example) then dereference p' S old value. The C operator "->" alSo dereferenceS itS left hand argument which iS aSSumed to point to a Structure or union of which the right hand argument iS a member. At firSt Sight the word "dereference" might be thought to mean "to cauSe to Stop referring" but itS meaning iS well eStabliShed in jargon.
