Arguments: slot-name stream &rest args
This macro is only valid within a with-stream-class form. The slot-name argument names a slot in the stream which is accessed very quickly. It is expected to contain a function object, which is funcall'ed along with the stream and the other args. The macro returns whatever values the function returns. This macro is useful for read-like operations, where the stream is the first argument of the function.
You must load the :iodefs module to use this
macro. Do that by evaluating (require :iodefs). (It
is not an error to evaluate that form if the module is already
loaded.) This macro is intended for implementing device-level
functionality and should not be used except for that purpose. See Simple-stream Description
in streams.htm for a description of the device-level.
See streams.htm for information on the simple-streams implementation in Allegro CL.
