[Discuss-gnuradio] UHD Interface - Difference between num samps rx

[Isaac Gerg]

Using USRP1.

Whats the difference between using this:
    Int32 total_num_samps = 1000;
    uhd::stream_cmd_t stream_cmd(uhd::stream_cmd_t::STREAM_MODE_START_CONTINUOUS);
    stream_cmd.num_samps = total_num_samps;
    stream_cmd.stream_now = true;
    m_pSdev->issue_stream_cmd(stream_cmd);

Versus using:
       Int32 sampsPerBlock = 1000;
        pBuff = new vector<complex<Float32> >(sampsPerBlock);
        size_t num_rx_samps = m_pDev->recv(&(pBuff->front()), pBuff->size(), md,uhd::io_type_t::COMPLEX_FLOAT32,uhd::device::RECV_MODE_FULL_BUFF);


What if total_num_samps and sampsPerBlock differ in length?
