## Implemented Interfaces

GUnixInputStream implements GPollableInputStream and GFileDescriptorBased.

## Properties

      "close-fd"                 gboolean              : Read / Write
      "fd"                       gint                  : Read / Write / Construct Only

## Description

GUnixInputStream implements GInputStream for reading from 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/gunixinputstream.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

### struct GUnixInputStream

    struct GUnixInputStream;

Implements GInputStream for reading from selectable unix file descriptors

### g_unix_input_stream_new ()

    GInputStream *      g_unix_input_stream_new             (gint fd,
                                                             gboolean close_fd);

Creates a new GUnixInputStream for the given `fd`.

If `close_fd` is `TRUE`, the file descriptor will be closed when the stream is closed.

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

### g_unix_input_stream_set_close_fd ()

    void                g_unix_input_stream_set_close_fd    (GUnixInputStream *stream,
                                                             gboolean close_fd);

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

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

Since 2.20

### g_unix_input_stream_get_close_fd ()

    gboolean            g_unix_input_stream_get_close_fd    (GUnixInputStream *stream);

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

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

Since 2.20

### g_unix_input_stream_get_fd ()

    gint                g_unix_input_stream_get_fd          (GUnixInputStream *stream);

Return the UNIX file descriptor that the stream reads from.

`stream` : | a GUnixInputStream
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 reads from.

Default value: -1

Since 2.20
