shell_nlip_input_register

int shell_nlip_input_register(shell_nlip_input_func_t nf, void *arg)

Registers a handler for incoming newtmgr messages. The shell receives the incoming data stream from the UART, and when it detects a NLIP frame, decodes the datagram, and calls the registered handler,nf.

The handler function is of type int (*shell_nlip_input_func_t)(struct os_mbuf *m, void *arg). The shell passes the incoming newtmgr message stored in a os_mbuf and the arg that was passed to the shell_nlip_input_register() function as arguments to the handler function.

Arguments

Arguments	Description
nf	Handler for incoming newtmgr datagrams.
arg	Argument that is passed to this handler, along with the datagram.

Returned values

Returns 0 on success.

Non-zero on failure.

Example

static int
nmgr_shell_in(struct os_mbuf *m, void *arg)
{
    ....
}

int 
nmgr_task_init(uint8_t prio, os_stack_t *stack_ptr, uint16_t stack_len)
{
    int rc;
    ....
    rc = shell_nlip_input_register(nmgr_shell_in, 
            (void *) &g_nmgr_shell_transport);
    if (rc != 0) {
        goto err;
    }
    ....
}
