Making the read side non-blocking doesn't affect the write side, and vice-versa.

Making the read side non-blocking doesn't affect the write side, and vice-versa.
- duped 2y agoThat is not true for pipes.
- caf 2y agoIt is, at least on Linux for ordinary pipe(2) pipes. I just wrote up a test to be sure: in the process with the read side, set it to non-blocking with fcntl(p, F_SETFL, O_NONBLOCK) then go to sleep for a long period. Dump a bunch of data into the writing side with the other process: the write() call blocks once the pipe is full as you would expect.
