device-buffer-length

Arguments: stream

Returns the desired length of buffers to be allocated for the stream, if any. This method may be called from almost anywhere (the exceptions are noted in the bulleted list below), and should return a value that is constant for each instance. The method may query the stream (to determine the optimum buffer length for the underlying device), and so the stream must exist before device-buffer-length methods are executed. Therefore, device-buffer-length methods must never be called by

Defined methods

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.
