sm

Arguments: slot-name stream

Returns the value of the named slot in the stream. If within a with-stream-class form a fast access (one or two memory reference instructions) is generated, otherwise a warning is given and an unoptimized slot-value is performed. See with-stream-class for further information and examples.

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.
