C++ (Cpp) network_rx Examples

Example #1

File: lwip-net.c Project: cnplab/mini-os

/* TODO: Use mini-os's blocking poll */
static void netfrontif_thread(void *argp)
{
    struct netif *netif = argp;
    struct netfrontif *nfi = netif->state;
    struct netfront_dev *dev = nfi->dev;

#ifdef CONFIG_SELECT_POLL
    int fd;
    fd_set rfds;
    struct timeval tv;

    fd = netfrontif_fd(netif);
    FD_ZERO(&rfds);

    tv.tv_sec = CONFIG_LWIP_SELECT_TIMEOUT;
    tv.tv_usec = 0;
#endif

    while (likely(!nfi->_thread_exit)) {
#ifdef CONFIG_SELECT_POLL
        FD_SET(fd, &rfds);
        select(fd + 1, &rfds, NULL, NULL, &tv);
#else
        schedule();
#endif
        network_rx(dev);
    }

    nfi->_thread_exit = 0;
}

Example #2

File: netfront.c Project: farewellkou/xen

void netfront_handler(evtchn_port_t port, struct pt_regs *regs, void *data)
{
    int flags;
    struct netfront_dev *dev = data;

    local_irq_save(flags);
    network_tx_buf_gc(dev);
    network_rx(dev);

    local_irq_restore(flags);
}

Example #3

File: netfront.c Project: a2k2/xen-unstable

ssize_t netfront_receive(struct netfront_dev *dev, unsigned char *data, size_t len)
{
    unsigned long flags;
    int fd = dev->fd;
    ASSERT(current == main_thread);

    dev->rlen = 0;
    dev->data = data;
    dev->len = len;

    local_irq_save(flags);
    network_rx(dev);
    if (!dev->rlen && fd != -1)
	/* No data for us, make select stop returning */
	files[fd].read = 0;
    /* Before re-enabling the interrupts, in case a packet just arrived in the
     * meanwhile. */
    local_irq_restore(flags);

    dev->data = NULL;
    dev->len = 0;
