## Description

GUnixOutputStream implements GOutputStream for writing to a unix file descriptor, including asynchronous operations. The file descriptor must be selectable, so it doesn't work with opened files.

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.

## Details

### GUnixOutputStream

    typedef struct _GUnixOutputStream GUnixOutputStream;

Implements GOutputStream for outputting to selectable unix file descriptors

### g_unix_output_stream_new ()

    GOutputStream *     g_unix_output_stream_new            (gint fd,
                                                             gboolean close_fd);

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.

`fd` : | a UNIX file descriptor
`close_fd` : | `TRUE` to close the file descriptor when done
Returns : | a new GOutputStream

### g_unix_output_stream_set_close_fd ()

    void                g_unix_output_stream_set_close_fd   (GUnixOutputStream *stream,
                                                             gboolean close_fd);

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

`stream` : | a GUnixOutputStream
`close_fd` : | `TRUE` to close the file descriptor when done

Since 2.20

### g_unix_output_stream_get_close_fd ()

    gboolean            g_unix_output_stream_get_close_fd   (GUnixOutputStream *stream);

Returns whether the file descriptor of `stream` will be closed when the stream is closed.

`stream` : | a GUnixOutputStream
Returns : | `TRUE` if the file descriptor is closed when done

Since 2.20

### g_unix_output_stream_get_fd ()

    gint                g_unix_output_stream_get_fd         (GUnixOutputStream *stream);

Return the UNIX file descriptor that the stream writes to.

`stream` : | a GUnixOutputStream
Returns : | The file descriptor of `stream`

Since 2.20

## Property Details

### The `"close-fd"` property

      "close-fd"                 gboolean              : Read / Write

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

Default value: TRUE

Since 2.20

### The `"fd"` property

      "fd"                       gint                  : Read / Write / Construct Only

The file descriptor that the stream writes to.

Default value: -1

Since 2.20
