DESCRIPTION

18       The function comedi_set_read_subdevice sets subdevice as the current
19       “read” subdevice if the subdevice supports streaming input commands.
20
21       No action is performed if subdevice is already the current “read”
22       subdevice.
23
24       Changes are local to the open file description for this device and have
25       no effect on other open file descriptions for the underlying device
26       node.
