### Class

# Soup MultipartInputStream

since: 3.0

#### Description [src]

    final class Soup.MultipartInputStream : Gio.FilterInputStream
      implements Gio.PollableInputStream {
      /* No available fields */
    }

Handles streams of multipart messages.

This adds support for the multipart responses. For handling the multiple parts the user needs to wrap the `GInputStream` obtained by sending the request with a `SoupMultipartInputStream` and use `soup_multipart_input_stream_next_part()` before reading. Responses which are not wrapped will be treated like non-multipart responses.

Note that although `SoupMultipartInputStream` is a `GInputStream`, you should not read directly from it, and the results are undefined if you do.

###### soup_multipart_input_stream_next_part_finish

Finishes an asynchronous request for the next part.

##### Methods inherited from GFilterInputStream (3)

###### g_filter_input_stream_get_base_stream

Gets the base stream for the filter stream.

since: 2.0

###### g_filter_input_stream_get_close_base_stream

Returns whether the base stream will be closed when `stream` is closed.

since: 2.0

###### g_filter_input_stream_set_close_base_stream

Sets whether the base stream will be closed when `stream` is closed.

since: 2.0

##### Methods inherited from GInputStream (19)

###### g_input_stream_clear_pending

Clears the pending flag on `stream`.

since: 2.0

###### g_input_stream_close

Closes the stream, releasing resources related to it.

since: 2.0

###### g_input_stream_close_async

Requests an asynchronous closes of the stream, releasing resources related to it. When the operation is finished `callback` will be called. You can then call `g_input_stream_close_finish()` to get the result of the operation.

since: 2.0

###### g_input_stream_close_finish

Finishes closing a stream asynchronously, started from g_input_stream_close_async().

since: 2.0

###### g_input_stream_has_pending

Checks if an input stream has pending actions.

since: 2.0

###### g_input_stream_is_closed

Checks if an input stream is closed.

since: 2.0

###### g_input_stream_read

Tries to read `count` bytes from the stream into the buffer starting at `buffer`. Will block during this read.

since: 2.0

###### g_input_stream_read_all

Tries to read `count` bytes from the stream into the buffer starting at `buffer`. Will block during this read.

since: 2.0

###### g_input_stream_read_all_async

Request an asynchronous read of `count` bytes from the stream into the buffer starting at `buffer`.

since: 2.44

###### g_input_stream_read_all_finish

Finishes an asynchronous stream read operation started with g_input_stream_read_all_async().

since: 2.44

###### g_input_stream_read_async

Request an asynchronous read of `count` bytes from the stream into the buffer starting at `buffer`. When the operation is finished `callback` will be called. You can then call `g_input_stream_read_finish()` to get the result of the operation.

since: 2.0

###### g_input_stream_read_bytes

Like g_input_stream_read(), this tries to read `count` bytes from the stream in a blocking fashion. However, rather than reading into a user-supplied buffer, this will create a new `GBytes` containing the data that was read. This may be easier to use from language bindings.

since: 2.34

###### g_input_stream_read_bytes_async

Request an asynchronous read of `count` bytes from the stream into a new `GBytes`. When the operation is finished `callback` will be called. You can then call `g_input_stream_read_bytes_finish()` to get the result of the operation.

since: 2.34

###### g_input_stream_read_bytes_finish

Finishes an asynchronous stream read-into-`GBytes` operation.

since: 2.34

###### g_input_stream_read_finish

Finishes an asynchronous stream read operation.

since: 2.0

###### g_input_stream_set_pending

Sets `stream` to have actions pending. If the pending flag is already set or `stream` is closed, it will return `FALSE` and set `error`.

since: 2.0

###### g_input_stream_skip

Tries to skip `count` bytes from the stream. Will block during the operation.

since: 2.0

###### g_input_stream_skip_async

Request an asynchronous skip of `count` bytes from the stream. When the operation is finished `callback` will be called. You can then call `g_input_stream_skip_finish()` to get the result of the operation.

since: 2.0

###### g_input_stream_skip_finish

Finishes a stream skip operation.

since: 2.0

##### Methods inherited from GObject (43)

Please see GObject for a full list of methods.

##### Methods inherited from GPollableInputStream (4)

###### g_pollable_input_stream_can_poll

Checks if `stream` is actually pollable. Some classes may implement `GPollableInputStream` but have only certain instances of that class be pollable. If this method returns `FALSE`, then the behavior of other `GPollableInputStream` methods is undefined.

since: 2.28

###### g_pollable_input_stream_create_source

Creates a `GSource` that triggers when `stream` can be read, or `cancellable` is triggered or an error occurs. The callback on the source is of the `GPollableSourceFunc` type.

since: 2.28

###### g_pollable_input_stream_is_readable

Checks if `stream` can be read.

since: 2.28

###### g_pollable_input_stream_read_nonblocking

Attempts to read up to `count` bytes from `stream` into `buffer`, as with g_input_stream_read(). If `stream` is not currently readable, this will immediately return `G_IO_ERROR_WOULD_BLOCK`, and you can use `g_pollable_input_stream_create_source()` to create a `GSource` that will be triggered when `stream` is readable.

since: 2.0

#### Properties

###### Soup.MultipartInputStream:message

The `SoupMessage`.

since: 3.0

##### Properties inherited from GFilterInputStream (2)

###### Gio.FilterInputStream:base-stream

The underlying base stream on which the I/O ops will be done.

since: 2.0

###### Gio.FilterInputStream:close-base-stream

Whether the base stream should be closed when the filter stream is closed.

since: 2.0

#### Signals

##### Signals inherited from GObject (1)

###### GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

since: 2.0
