ngtcp2_conn_set_tls_error
=========================

Synopsis
--------

*#include <ngtcp2/ngtcp2.h>*

.. function:: void ngtcp2_conn_set_tls_error(ngtcp2_conn *conn, int liberr)

    
    `ngtcp2_conn_set_tls_error` sets the TLS related error *liberr* in
    *conn*.  *liberr* must be one of ngtcp2 library error codes (which
    is defined as NGTCP2_ERR_* macro, such as
    :macro:`NGTCP2_ERR_DECRYPT`).  In general, error code should be
    propagated via return value, but sometimes ngtcp2 API is called
    inside callback function of TLS stack, and it does not allow to
    return ngtcp2 error code directly.  In this case, implementation
    can set the error code (e.g.,
    :macro:`NGTCP2_ERR_MALFORMED_TRANSPORT_PARAM`) using this function.
