class: GFileInputStream

[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

GFileInputStream (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 GInputStream.
- @r A GInputStream object.
asSeekable ()

Wraps this handle as GSeekable.
- @r A GSeekable 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..
- @r a #GFileInfo, or %NULL on error..
query_info_async (string attributes, int io_priority, object cancellable, user_data)

Queries the stream information asynchronously. When the operation is finished @callback will be called. You can then call g_file_input_stream_query_info_finish() to get the result of the operation. For the synchronous version of this function, see g_file_input_stream_query_info(). If @cancellable is not %NULL, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error %G_IO_ERROR_CANCELLED will be set
- @p attributes is a file attribute query string..
- @p io_priority is the I/O priority of the request.
- @p cancellable is optional #GCancellable object, %NULL to ignore..
- @p callback is a #GAsyncReadyCallback to call when the request is satisfied.
- @p user_data is the data to pass to callback function.
- @r None.
query_info_finish (object result)

Finishes an asynchronous info query operation.
- @p result is a #GAsyncResult..
- @r #GFileInfo..
