Gio.OutputStream::splice_finish

function vfunc_splice_finish(result: Gio.AsyncResult): Number(gssize) {
}

Finishes an asynchronous stream splice operation.

result: a Gio.AsyncResult.
Returns: a #gssize of the number of bytes spliced. Note that if the number of bytes spliced is greater than %G_MAXSSIZE, then that will be returned, and there is no way to determine the actual number of bytes spliced.
