About FIFO |
Description |
Reads the next specified number of data points from the FIFO buffer. The data is returned in 32 bit real/imaginary pair. Data is cleared as it is read. Note: This method is the slowest way to transfer data using COM. However, it is supported by all COM client programming languages. For better performance, try using DataInCompactForm. |
