device-finish-record

Arguments: stream blocking action

Performs record-oriented operations on stream. Simple-streams have a record-end slot that normally has a nil value. When the slot is set to a numeric value, it is interpreted by the read or write operation as the location in the buffer of the record-end or break. device-finish-record is then called, and the return value is interpreted based on the action specified and the value of blocking. action is typically one of :input, :output, or :prime-input (see the discussion on "priming" in the second bulleted paragraph below). blocking is a boolean which specifies whether or not the method should block during its operation, or else return immediately.

The return value is either true, meaning success, or nil, meaning failure. The interpretation of the nil return depends on the value of the blocking argument; if nil, then device-finish-record failed to complete the requested task. If blocking was true, then a return of nil means an eof was encountered (if action was :input or :prime-input), or an error occurred (if action was :output).

Allegro CL offers calls to device-finish-record under the following circumstances:

There are no usable methods defined.

See streams.htm for information on the simple-streams implementation in Allegro CL. The older but still supported Gray streams implementation is described in gray-streams.htm.
