I have 2 python programs. One is the reader

fifo_read=open('buffer','r')
while True:
    data=fifo_read.read(1)
    print('"',data,'"read from buffer')

and the other is the writer

import time

fifo_write=open('./buffer','w')

while True:
    fifo_write.write('a')
    fifo_write.flush()
    time.sleep(1)

The problem that I am facing is, as soon as I terminate the writer with Ctrl+C, the reader continues reading "" from the FIFO. For my purposes, I want the reader to block until another writer starts sometime in the future and starts writing to the FIFO. But this is not happening in this case.

    What do you expect read to do when you get to the end of the file? Also, why do you call it FIFO read, you're just opening a file. – matt Oct 11 '21 at 11:44

    Read returns an emtpy string when you're at the end of your "file/device" so you need to check for an empty string. There are tools in the link I provided for doing that. https://docs.python.org/3/library/ipc.html – matt Oct 11 '21 at 12:29
