flushinput

Remove data from input buffer

Syntax

flushinput(obj)

Arguments

obj

An interface object or an array of interface objects.

Description

flushinput(obj) removes data from the input buffer associated with obj.

Tips

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.

Introduced before R2006a
