*#include <ngtcp2/ngtcp2.h>*

.. function:: ngtcp2_ssize ngtcp2_encode_transport_params( uint8_t *dest, size_t destlen, ngtcp2_transport_params_type exttype, const ngtcp2_transport_params *params)

    
    `ngtcp2_encode_transport_params` encodes *params* in *dest* of
    length *destlen*.
    
    If *dest* is NULL, and *destlen* is zero, this function just
    returns the number of bytes required to store the encoded transport
    parameters.
