Gio.UnixFDList.peek

### Method

# Gio UnixFDListpeek

unstable since: 2.90

#### Declaration [src]

    int
    g_unix_fd_list_peek (
      GUnixFDList* list,
      size_t index_
    )

#### Description [src]

Gets a file descriptor out of `list`.

`index_` specifies the index of the file descriptor to get. It is a programmer error for `index_` to be out of range; see `g_unix_fd_list_get_length()`.

This will always return a valid (non-negative) file descriptor.

After this call, the descriptor remains the property of `list`. The caller must not close it. The descriptor is valid only until `list` is changed in any way.

Available since: 2.90

#### Parameters

`index_`

  Type: `size_t`

  The index into the list.

#### Return value

Type: `int`

The file descriptor.
