ngtcp2_decode_transport_params_new
==================================

Synopsis
--------

*#include <ngtcp2/ngtcp2.h>*

.. function:: int ngtcp2_decode_transport_params_new( ngtcp2_transport_params **pparams, uint32_t flags, ngtcp2_transport_params_type exttype, const uint8_t *data, size_t datalen, const ngtcp2_mem *mem)

    
    `ngtcp2_decode_transport_params_new` decodes transport parameters
    in *data* of length *datalen*, and stores the result in the object
    allocated dynamically.  The pointer to the allocated object is
    assigned to *\*pparams*.  Unlike `ngtcp2_decode_transport_params`,
    all direct and indirect fields are also allocated dynamically if
    needed.
    
    *flags* is bitwise OR of zero or more of
    :macro:`NGTCP2_TRANSPORT_PARAMS_DECODE_FLAG_*
    <NGTCP2_TRANSPORT_PARAMS_DECODE_FLAG_NONE>`.  If
    :macro:`NGTCP2_TRANSPORT_PARAMS_DECODE_FLAG_IGNORE_MISSING_REQUIRED_FIELDS`
    is set, this function does not check the missing required fields,
    and :macro:`NGTCP2_ERR_REQUIRED_TRANSPORT_PARAM` will not be
    returned.
    
    *mem* is a memory allocator to allocate memory.  If *mem* is
    ``NULL``, the memory allocator returned by `ngtcp2_mem_default()`
    is used.
    
    If the optional parameters are missing, the default value is
    assigned.
    
    `ngtcp2_transport_params_del` frees the memory allocated by this
    function.
    
    This function returns 0 if it succeeds, or one of the following
    negative error codes:
    
    :macro:`NGTCP2_ERR_REQUIRED_TRANSPORT_PARAM`
        The required parameter is missing.
    :macro:`NGTCP2_ERR_MALFORMED_TRANSPORT_PARAM`
        The input is malformed.
    :macro:`NGTCP2_ERR_NOMEM`
        Out of memory.
