class: FileInputStream

[18:7] extends: object

GFileInputStream provides input streams that take their content from a file. GFileInputStream implements [iface@Gio.Seekable], which allows the input stream to jump to arbitrary positions in the file, provided the filesystem of the file allows it. To find the position of a file input stream, use [method@Gio.Seekable.tell]. To find out if a file input stream supports seeking, use [vfunc@Gio.Seekable.can_seek]. To position a file input stream, use [vfunc@Gio.Seekable.seek].

Methods

  • FileInputStream (Handle = null)

    Creates a new FileInputStream by wrapping a native handle or another wrapper.

    • @p Handle is the native handle or another wrapper whose handle to adopt.
  • toNativeHandle (Source)

    Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

    • @p Source is the raw handle, raw buffer, wrapper, or null.
    • @r A raw pointer carrier or null when no pointer is present.
  • getLib ()

    Returns the opened native library for this generated wrapper.

    • @r The opened native library.
  • handle ()

    Returns the wrapped NativeHandle.

    • @r The wrapped NativeHandle.
  • isNull ()

    Returns true when the wrapped handle is null.

    • @r A bool.
  • describe ()

    Returns a small string for debugging generated wrappers.

    • @r A string.
  • asInputStream ()

    Wraps this handle as InputStream.

    • @r A InputStream object.
  • asSeekable ()

    Wraps this handle as Seekable.

    • @r A Seekable object.
  • query_info (string attributes, object cancellable)

    Queries a file input stream the given @attributes. This function blocks while querying the stream. For the asynchronous (non-blocking) version of this function, see g_file_input_stream_query_info_async(). While the stream is blocked, the stream will set the pending flag internally, and any other operations on the stream will fail with %G_IO_ERROR_PENDING.

    • @p attributes is a file attribute query string..
    • @p cancellable is optional #GCancellable object, %NULL to ignore..
  • query_info_finish (object result)

    Finishes an asynchronous info query operation.

    • @p result is a #GAsyncResult..
