Notes

Example

Here is an example where newtmgr protocol handler is controlling whether echoing is on or off. Newtmgr, the tool, turns echoing off when it's transmitting large chunks of data to target board.

static int
nmgr_def_console_echo(struct nmgr_jbuf *njb)
{
    int echo_on = 1;
    int rc;
    struct json_attr_t attrs[3] = {
        [0] = {
            .attribute = "echo",
            .type = t_integer,
            .addr.integer = &echo_on,
            .nodefault = 1
        },
        [1] = {
            .attribute = NULL
        }
    };

    rc = json_read_object(&njb->njb_buf, attrs);
    if (rc) {
        return OS_EINVAL;
    }

    if (echo_on) {
        console_echo(1);
    } else {
        console_echo(0);
    }
    return (0);
}
