Expand description

\brief This function feeds an input buffer into an ongoing message-digest computation.

             You must call mbedtls_md_starts() before calling this
             function. You may call this function multiple times.
             Afterwards, call mbedtls_md_finish().

\param ctx The generic message-digest context. \param input The buffer holding the input data. \param ilen The length of the input data.

\return \c 0 on success. \return #MBEDTLS_ERR_MD_BAD_INPUT_DATA on parameter-verification failure.
