Examples of org.jruby.util.io.ChannelDescriptor.dup2()

org.jruby.util.io.ChannelDescriptor.dup2()
Mimics the POSIX dup2(2) function, returning a new descriptor that references the same open channel but with a specified fileno. @param fileno The fileno to use for the new descriptor @return A duplicate ChannelDescriptor based on this one
