(v13) device_buffersize determine file buffer size
This page applies to Harlequin v13.1r0 and later; and to Harlequin Core but not Harlequin MultiRIP
int32 device_buffersize ( DEVICELIST *dev);
This routine is called when a file is opened on the device. It should return the size of the buffer that the device requires for best operation. If the device_type
structure has NULL
in this function slot, or if the specified routine returns a number less than zero, then the DEVICESMALLBUFF
flag is examined to determine the size of the buffer.
