with-object-byte-storage Statement Macro

Provides the pinned address of the repeated byte storage of an object within the scope of the body of the code.

Macro Call:

with-object-byte-storage (name  = object)
  body
end [with-object-byte-storage]

Parameters:

• name – A Dylan variable name.

• object – A Dylan object with repeated byte storage.
