/**
* soup_form_request_new_from_multipart:
* @uri: the URI to send the form data to
* @multipart: a "multipart/form-data" #SoupMultipart
*
* Creates a new %SoupMessage and sets it up to send @multipart to
* @uri via POST.
*
* To send a <literal>"multipart/form-data"</literal> POST, first
* create a #SoupMultipart, using %SOUP_FORM_MIME_TYPE_MULTIPART as
* the MIME type. Then use soup_multipart_append_form_string() and
* soup_multipart_append_form_file() to add the value of each form
* control to the multipart. (These are just convenience methods, and
* you can use soup_multipart_append_part() if you need greater
* control over the part headers.) Finally, call
* soup_form_request_new_from_multipart() to serialize the multipart
* structure and create a #SoupMessage.
*
* Return value: (transfer full): the new %SoupMessage
*
* Since: 2.26
