attrvalidstextDisplay attribute to give to new occurrences.Validation bits to give to new occurrences.Text to put into new occurrences.AS_GDATA_FUNCAS_GDATA_FUNC expects a routine that gets the data of an occurrence in ascrolling array. The routine might be called because the occurrence scrolledonscreen, or in response to a request for data from a C or JPL routine, forexample, a call by sm_getfield.Occurrence data contains text, display attributes, and validation flags. Pantherallocates a buffer to hold this data and passes a pointer to the buffer in the textmember. The routine should update the attr, text, and valids members in thestructure with values previously passed in by the AS_PDATA_FUNC routine,although a clever driver can manufacture them.Return value of 0 indicates success; -1 indicates failure.Note:An empty occurrence must be blank-filled.Input parameters (and their descriptions) are:scrolldataitemlentextPointer to the driver's internal buffer.Occurrence number to get.Length of the occurrence. Represents the size ofPanther's buffer; the scrolling driver should notoverrun this length.Buffer to get the text.Output parameters (and their descriptions) are:attrtextDisplay attribute of the occurrence.The routine should fill the buffer pointed to by text withthe text of the occurrence as passed to the routine byPDATA.A-6 JAM Documentation: Alternative Scrolling
