<para>A priority is an enumerated value of type <computeroutput>unsigned</computeroutput>. Currently, Taskflow defines three priority levels, <computeroutput>HIGH</computeroutput>, <computeroutput>NORMAL</computeroutput>, and <computeroutput>LOW</computeroutput>, starting from 0, 1, to 2. That is, the lower the value, the higher the priority. </para>

Performs a key-value merge that copies elements from <computeroutput>[a_keys_first, a_keys_last)</computeroutput> and <computeroutput>[b_keys_first, b_keys_last)</computeroutput> into a single range, <computeroutput>[c_keys_first, c_keys_last + (a_keys_last - a_keys_first) + (b_keys_last - b_keys_first))</computeroutput> such that the resulting range is in ascending key order.</para>
<para>At the same time, the merge copies elements from the two associated ranges <computeroutput>[a_vals_first + (a_keys_last - a_keys_first))</computeroutput> and <computeroutput>[b_vals_first + (b_keys_last - b_keys_first))</computeroutput> into a single range, <computeroutput>[c_vals_first, c_vals_first + (a_keys_last - a_keys_first) + (b_keys_last - b_keys_first))</computeroutput> such that the resulting range is in ascending order implied by each input element&apos;s associated key.</para>
<para>For example, assume:<itemizedlist>
<listitem><para><computeroutput>a_keys</computeroutput> = {1, 8};</para>
</listitem><listitem><para><computeroutput>a_vals</computeroutput> = {2, 1};</para>

<para>After the merge, we have:<itemizedlist>
