stream-package

Arguments: cg-stream

Returns the package in which unqualified symbols will be read from and printed to in cg-stream, which should be a cg-stream.

An application may call (setf stream-package) to declare what the package of a cg-stream is. Then whenever certain Common Graphics functions are called that may do a Lisp read on a string that is associated with the cg-stream (or a Lisp write on an arbitrary Lisp object), then *package* will be bound to the stream-package of the stream at that time.

In particular, some methods of selected-symbol and selected-form use the stream-package when reading from strings, and the paste-selection method for text-edit-pane uses it when printing Lisp objects. Other exported Common Graphics functions may call these functions, and the IDE does as well.

The value passed to (setf stream-package) may be either a package object, a package name, or nil to indicate no associated package. When nil, no rebinding of *package* is done. The default stream-package is nil.
