module Gio::PollableOutputStream

Overview

GPollableOutputStream is implemented by Gio::OutputStreams that can be polled for readiness to write. 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 GPollableOutputStream but have only certain instances of that class be pollable. If Gio::PollableOutputStream#can_poll returns false, then the behavior of other GPollableOutputStream methods is undefined.

Direct including types

• Gio::ConverterOutputStream
• Gio::MemoryOutputStream
• Gio::UnixOutputStream

Defined in:

lib/gi-crystal/src/auto/gio-2.0/pollable_output_stream.cr

Constructors

• .cast(obj : GObject::Object) : self

  Cast a GObject::Object to self, throws a TypeCastError if the cast can't be made.

Class Method Summary

• .cast?(obj : GObject::Object) : self | Nil
• .g_type : UInt64
