Synopsis
--------

*#include <nghttp2v2/nghttp2.h>*

.. function:: int nghttp2_conn_read(nghttp2_conn *conn, const uint8_t *data, size_t datalen, nghttp2_tstamp ts)

    
    `nghttp2_conn_read` processes the incoming data pointed by *data*
    of length *datalen*.  *ts* is the timestamp of this call.  This
    function processes all input data.
    
    If this function returns an error code, the error is unrecoverable,
    therefore the application should close the underlying connection
    without calling any nghttp2 API for *conn*.
    
    This function returns 0 if it succeeds, or one of the following
    negative error codes:
    
    :macro:`NGHTTP2_ERR_NOMEM`
        Out of memory.
    :macro:`NGHTTP2_ERR_CALLBACK_FAILURE`
        User callback failed.
    :macro:`NGHTTP2_ERR_EXCESSIVE_LOAD`
        The remote endpoint exhibits the behavior that causes the
        excessive load to the local endpoint.
