## Public Member Functions

virtual | ~UnixOutputStream ()
GUnixOutputStream* | gobj ()
| Provides access to the underlying C GObject.
const GUnixOutputStream* | gobj () const
| Provides access to the underlying C GObject.
GUnixOutputStream* | gobj_copy ()
| Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.
void | set_close_fd (bool close_fd=true)
| Sets whether the file descriptor of stream shall be closed when the stream is closed.
bool | get_close_fd () const
| Return value: `true` if the file descriptor is closed when done.
int | get_fd () const
| Return the UNIX file descriptor that the stream writes to.
Glib::PropertyProxy_ReadOnly< int > | property_fd () const

## Detailed Description

UnixOutputStream implements OutputStream for writing to a a unix file descriptor, including asynchronous operations.

The file descriptor much be selectable, so it doesn't work with opened files.

Since glibmm 2.16:

Glib::PropertyProxy_ReadOnly<bool> Gio::UnixOutputStream::property_close_fd | ( |  | ) | const

Whether to close the file descriptor when the stream is closed.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy<bool> Gio::UnixOutputStream::property_close_fd | ( |  | ) |

Whether to close the file descriptor when the stream is closed.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly<int> Gio::UnixOutputStream::property_fd | ( |  | ) | const

The file descriptor to write to.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

void Gio::UnixOutputStream::set_close_fd | ( | bool | close_fd = `true` | ) |

Sets whether the file descriptor of stream shall be closed when the stream is closed.

Since glibmm 2.20:

Parameters:

  | close_fd | `true` to close the file descriptor when done.

Glib::RefPtr< Gio::UnixOutputStream > wrap | ( | GUnixOutputStream * | object,
|  | bool | take_copy = `false` |
| ) |  |  | `[related]`

A Glib::wrap() method for this object.

Parameters:

  | object | The C instance.
  | take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns:
  A C++ instance that wraps this C instance.
