A pn_link_t may be either sender or a receiver but never both.</p>
 <p>A pn_link_t object maintains a pointer to the <em>current</em> delivery within the ordered sequence of deliveries contained by the link (See <a class="el" href="group__link.html#gad7e426b0cc4759568b3fd2b4fb176260" title="Get the current delivery for a link.">pn_link_current</a>). The <em>current</em> delivery is the target of a number of operations associated with the link, such as sending (<a class="el" href="group__link.html#gaa825fac21730f3f9fff37d156e5f88e9" title="Send message data for the current delivery on a link.">pn_link_send</a>) and receiving (<a class="el" href="group__link.html#ga06c97ce7396973dca0d311567f25f95a" title="Receive message data for the current delivery on a link.">pn_link_recv</a>) message data. </p>

 <p>Get the credit balance for a link. </p>
 <p>Links use a credit based flow control scheme. Every receiver maintains a credit balance that corresponds to the number of deliveries that the receiver can accept at any given moment. As more capacity becomes available at the receiver (see <a class="el" href="group__link.html#gafec44cf1c79ec03f3ac009e1879e71a9" title="Grant credit for incoming deliveries on a receiver.">pn_link_flow</a>), it adds credit to this balance and communicates the new balance to the sender. Whenever a delivery is sent/received, the credit balance maintained by the link is decremented by one. Once the credit balance at the sender reaches zero, the sender must pause sending until more credit is obtained from the receiver.</p>
 <p>Note that a sending link may still be used to send deliveries even if pn_link_credit reaches zero, however those deliveries will end up being buffered by the link until enough credit is obtained from the receiver to send them over the wire. In this case the balance reported by <a class="el" href="group__link.html#ga55428637f3b8c446efd5fea3f26c932d" title="Get the credit balance for a link.">pn_link_credit</a> will go negative.</p>
