/* DESCRIPTION */
/* */
/* This function sets up a function pointer that TLS will invoke when */
/* a re-negotiation request is received from a remote host. This */
/* happens when the remote host sends a ClientHello or HelloRequest */
/* (client and server hosts, respectively) during an active session. */
/* The callback is used to notify the application when a */
/* re-negotiation has been requested. The callback should return */
/* NX_SUCCESS to continue the re-negotiation handshake or a non-zero */
/* error code to abort the current TLS session. */
