       comedi_poll - force updating of streaming buffer

SYNOPSIS

       #include <comedilib.h>

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

DESCRIPTION

       The function comedi_poll() is used on a subdevice that has a Comedi command in progress in
       order to update the streaming buffer.  If supported by the driver, all  available  samples
       are copied to the streaming buffer.  These samples may be pending in DMA buffers or device
       FIFOs.  If sucessful, the number of additional bytes available is returned.  If  there  is
       an error, -1 is returned.
