Ralf Schmitt <[EMAIL PROTECTED]> added the comment:
The open('fifo', 'rb') already blocks. One has to use os.fdopen with
O_NONBLOCK to prevent blocking.
fd=os.open('fifo', os.O_RDONLY | os.O_NONBLOCK)
and then use
stat.S_ISFIFO(os.fstat(fd).st_mode)
to check if this is a fifo.
Checking with os.stat before opening with open will result in a race
condition.
