List of waitReadable() Examples

Examples of waitReadable()

org.jruby.util.io.OpenFile.waitReadable()
Logic to match (as well as possible) rb_io_wait_readable from MRI. We do not have the luxury of treating all file descriptors the same, so there's a bit of special-casing here when the channel is not selectable. Note also the EBADF on closed channels; I believe this is what *would happen in MRI if we always called the selection logic and were given a closed channel. MRI: rb_io_wait_readable
