Remove data from input buffer
flushinput(obj)
| An interface object or an array of interface objects. |
flushinput(obj) removes data from the
input buffer associated with obj.
After the input buffer is flushed, the BytesAvailable
property is automatically configured to 0.
If flushinput is called during an asynchronous (nonblocking)
read operation, the data currently stored in the input buffer is flushed and the
read operation continues. You can read data asynchronously from the instrument using
the readasync function.
The input buffer is automatically flushed when you connect an object to the
instrument with the fopen function.
You can clear the output buffer with the flushoutput function. You can
clear the hardware buffer for GPIB and VXI instruments with the clrdevice function.
