This function combines some common tasks which will normally be performed
when setting up a triggered buffer. It will allocate the buffer and the
pollfunc.
</p><p>
Before calling this function the indio_dev structure should already be
completely initialized, but not yet registered. In practice this means that
this function should be called right before <code class="function">iio_device_register</code>.
</p><p>
To free the resources allocated by this function call
<code class="function">iio_triggered_buffer_cleanup</code>.
