Synopsis
--------

*#include <nghttp2/nghttp2.h>*

.. function:: void nghttp2_session_callbacks_set_on_invalid_header_callback( nghttp2_session_callbacks *cbs, nghttp2_on_invalid_header_callback on_invalid_header_callback)

    
    Sets callback function invoked when a invalid header name/value
    pair is received.  If both
    `nghttp2_session_callbacks_set_on_invalid_header_callback()` and
    `nghttp2_session_callbacks_set_on_invalid_header_callback2()` are
    used to set callbacks, the latter takes the precedence.
