## Object Hierarchy

        GObject
        ╰── GInputStream
            ╰── GUnixInputStream

## Implemented Interfaces

GUnixInputStream implements GPollableInputStream and GFileDescriptorBased.

## Includes

    #include <gio/gunixinputstream.h>

## 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.

## Functions

### 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.

#### Parameters

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.

#### Parameters

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.

#### Parameters

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.

#### Parameters

stream | a GUnixInputStream |

#### Returns

The file descriptor of `stream`

Since 2.20

## Types and Values

### struct GUnixInputStream

    struct GUnixInputStream;

Implements GInputStream for reading from selectable unix file descriptors

## Property Details

### The `“close-fd”` property

      “close-fd”                 gboolean

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

Flags: Read / Write

Default value: TRUE

Since 2.20

### The `“fd”` property

      “fd”                       gint

The file descriptor that the stream reads from.

Flags: Read / Write / Construct Only

Default value: -1

Since 2.20
