int ms);
The fido_dev_get_touch_begin
() function
initiates a touch request on dev.
The fido_dev_get_touch_status
() function
continues an ongoing touch request on dev, blocking up
to ms milliseconds. On success,
touched will be updated to reflect the touch request
status. If touched is 1, the device was touched, and
the touch request is terminated. If touched is 0, the
application may call fido_dev_get_touch_status
() to
continue the touch request, or fido_dev_cancel
() to
terminate it.
fido_dev_get_touch_begin
()
and fido_dev_get_touch_status
() are defined in
<fido/err.h>
. On success,
FIDO_OK
is returned.
fido_dev_get_touch_status
() function will cause a
command to be transmitted to U2F authenticators. These transmissions should
not exceed a frequency of 5Hz.
