public interface PollableInputStream : InputStream

`GPollableInputStream` is implemented by [class@Gio.

InputStream]s that can be polled for readiness to read. This can be used when interfacing with a non-GIO API that expects UNIX-file-descriptor-style asynchronous I/O rather than GIO-style.

Some classes may implement `GPollableInputStream` but have only certain instances of that class be pollable. If [ method@Gio.PollableInputStream.can_poll] returns false, then the behavior of other `GPollableInputStream` methods is undefined.

Methods:

public abstract bool can_poll ()
Checks if this is actually pollable.
public abstract PollableSource create_source (Cancellable? cancellable = null)
Creates a SocketSource that triggers when this can be read, or cancellable is triggered or an error occurs.
public abstract bool is_readable ()
Checks if this can be read.
public ssize_t read_nonblocking (uint8[] buffer, Cancellable? cancellable = null) throws Error
Attempts to read up to buffer.length bytes from this into buffer, as with read.
public abstract ssize_t read_nonblocking_fn (uint8[] buffer) throws Error
