Name
Ptr Function
Syntax
function Ptr(Value: Integer): Pointer;
Description
The Ptr function type casts the
Value to an untyped Pointer.
The Ptr function is not a real
function.
Tips and Tricks
Calling Ptr is just like casting a value to a
Pointer. If you can, you should cast to a specific
pointer type, such as PInt64 instead of using an
untyped Pointer. Typed pointers provide more type
safety.
