NAME

       comedi_set_read_subdevice - set streaming input subdevice

SYNOPSIS

       #include <comedilib.h>

       int comedi_set_read_subdevice(comedi_t * device, unsigned int subdevice);

STATUS

       Works for Linux "in-tree" Comedi since kernel version 3.19.

DESCRIPTION

       The function comedi_set_read_subdevice sets subdevice as the current “read” subdevice if
       the subdevice supports streaming input commands.

       No action is performed if subdevice is already the current “read” subdevice.

       Changes are local to the open file description for this device and have no effect on other
       open file descriptions for the underlying device node.

RETURN VALUE

       On success, 0 is returned. On failure, -1 is returned.
