Expand description

\brief This function calculates the message-digest checksum result of the contents of the provided file.

            The result is calculated as
            Output = message_digest(file contents).

\param md_info The information structure of the message-digest algorithm to use. \param path The input file name. \param output The generic message-digest checksum result.

\return \c 0 on success. \return #MBEDTLS_ERR_MD_FILE_IO_ERROR on an I/O error accessing the file pointed by \p path. \return #MBEDTLS_ERR_MD_BAD_INPUT_DATA if \p md_info was NULL.
