class Gio::UnixOutputStream

Overview

#GUnixOutputStream implements #GOutputStream for writing to a UNIX file descriptor, including asynchronous operations. (If the file descriptor refers to a socket or pipe, this will use poll() to do asynchronous I/O. If it refers to a regular file, it will fall back to doing asynchronous I/O in another thread.)

Note that <gio/gunixoutputstream.h> belongs to the UNIX-specific GIO interfaces, thus you have to use the gio-unix-2.0.pc pkg-config file when using it.

Constructor Detail

def self.new(fd : Int32, close_fd : Bool) : self #

Creates a new #GUnixOutputStream for the given fd.

If close_fd, is true, the file descriptor will be closed when the output stream is destroyed.

def self.new #

Initialize a new UnixOutputStream.


[View source]
def self.new(*, close_fd : Bool | Nil = nil, fd : Int32 | Nil = nil) #
