17. `O_NONBLOCK` flag in FIFOs
What is the significance of the `O_NONBLOCK` flag when opening a FIFO?
gaurav133232 July 4

O_NONBLOCK helps in preventing blocking conditions for e.g if there's a block on write or block on read, the process needs to wait for the other one to complete communication, rather it just returns the error code and exits.
