Declare Operator -> ( ByRef lhs As T Pointer ) As U

Note that Operator -> (Pointer to member access) returns a reference. As of 02.27.07, FreeBASIC syntax does not support returning references. When it does, this syntax will need to be changed.

result = lhs -> rhs

lhs
T
rhs
U

Returns a reference to the member specified by rhs.

Operator -> (Pointer to member access) returns a reference to a member of an object through a pointer to that object. It has the effect of dereferencing a pointer to an object, then using Operator . (Member Access). For example, "p->member" is equivalent to "x.member", if x is an object of user-defined type and p is a pointer to an object of the same type.

This operator can be overloaded for user-defined types.

Type rect
    x As Integer
    y As Integer
End Type

Dim r As rect
Dim rp As rect Pointer = @r

rp->x = 4
rp->y = 2

Print "x = " & rp->x & ", y = " & rp->y
Sleep
