CLEAR INPUT BUFFER

Good day!

I have a problem with Python and the input buffer.
My application must read a barcode from PS2 and then
process it.
The problem is: i have to discard all
characters inserted in buffer while Elaborate(data)
is running.
I tried to clear the buffer using sys.stdin.flush() but
it seem not work.

proc Principale() :
while True
# sys.stdin.flush()
data = sys.stdin.readline()
Elaborate(data)


proc Elaborate() :
sleep(5)


I'll apreciate any help!
Thanks

 

In general you can't flush the standard input,
it is one of those undefined behaviors in C.

To read the input until an end-of-file is reached
use read() instead of readline().

Now I try.
Thanks.
