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