TSHttpTxnNextHopStrategyFind
****************************

Synopsis
========

.. code-block:: cpp

    #include <ts/ts.h>

.. function:: TSStrategy TSHttpTxnNextHopStrategyFind(TSHttpTxn txnp, const char *name)

Description
===========

Gets a pointer to the specified :arg:`name` NextHopSelectionStrategy.
This may be nullptr indicating that no strategy exists with the given
name, or that no rewrite table or strategy factory existed when the
transaction started.

This function uses the transaction :arg:`txnp` to get access to the
NextHopStrategyFactory associated with the current configuration.

.. note::

   :arg:`name` must not be ``nullptr``. Passing a null name is an API
   violation and will abort the process in default builds.

.. note::

   This returned pointer must not be freed and the contents must not
   be changed.
   Strategy pointers held by plugins become invalid when ATS configs
   are reloaded and must be re-obtained during :func:`TSRemapNewInstance`

Deprecated
==========

.. function:: void const *TSHttpTxnNextHopNamedStrategyGet(TSHttpTxn txnp, const char *name)

   .. deprecated:: 11.0.0
      Use :func:`TSHttpTxnNextHopStrategyFind`. This 10.2 name will be
      removed in a future major release.

   Forwards to :func:`TSHttpTxnNextHopStrategyFind`.
