SYMBOL and NAME
-> - arrow operator
SYNOPSIS
p -> X
TYPES
p pointer to an lvalue
X identifier
return lvalue
DESCRIPTION
p->X returns the same as (*p).X. Thus the current value of *p is
to be an object of a type for which X identifies one element.
p->X then returns the lvalue corresponding to that element of the
value of *p.
The expression *p.X will cause a runtime error since this is
interpreted as *(p.X) in which p is expected to be an object of
an appropriate type.
Spaces or tabs on either side of -> are optional.
EXAMPLE
; obj pair {one, two}
; obj pair A; obj pair B
; p = &A
; p->one = 1; p->two = 2
; A
obj pair {1, 2}
; A->two = &B
; p->one = 3; p->two = 4
; *p
obj pair {3, 4}
; B = {5,6}
; *p->two
