Package poller is a file-descriptor multiplexer. It allows concurrent Read and Write operations from and to multiple file-descriptors without allocating one OS thread for every blocked operation. It operates similarly to Go's netpoller (which multiplexes network connections) without requiring special support from the Go runtime. It can be used with tty devices, character devices, pipes, FIFOs, and any file-descriptor that is poll-able, can be used with select(2), epoll(7), etc.

In addition, package poller allows the user to set timeouts (deadlines) for read and write operations, and also allows for safe cancellation of blocked read and write operations; a Close from another go-routine safely cancels ongoing (blocked) read and write operations.

It's an active fork of https://github.com/npat-efault/poller.
