What does "w+" mean in IO.open ?
in [Ruby]

From: Iñaki Baz Castillo on 7 Jan 2010 09:41 Hi, the rdoc says that "w+" means: "w+": Read-write, truncates existing file to zero length or creates a new file for reading and writing. however in a post I've read: output = open("my_pipe", "w+") # the w+ means we don't block Is it true? AFAIK it's not correct as you open a IO and later use bocking or non-blocking methods. Do I miss something? Thanks. -- Iñaki Baz Castillo <ibc(a)aliax.net>
