TSMimeHdrCopy
*************

Synopsis
========

.. code-block:: cpp

    #include <ts/ts.h>

.. function:: TSReturnCode TSMimeHdrCopy(TSMBuffer dest_bufp, TSMLoc dest_offset, TSMBuffer src_bufp, TSMLoc src_offset)

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

Copies the contents of the MIME header located at :arg:`src_loc` within
:arg:`src_bufp` to the MIME header located at :arg:`dest_loc` within
:arg:`dest_bufp`.

:c:func:`TSMimeHdrCopy` works correctly even if :arg:`src_bufp` and
:arg:`dest_bufp` point to different marshal buffers.

.. important::

   You must create the destination MIME header before copying into
   it, using :c:func:`TSMimeHdrCreate`.
