File.newTmpDirAsync

void newTmpDirAsync(string tmpl,  int  ioPriority,  gio.cancellable.Cancellable cancellable =  null,  gio.types.AsyncReadyCallback callback =  null)

Asynchronously creates a directory in the preferred directory for temporary files (as returned by [glib.global.getTmpDir]) as [glib.dir.Dir.makeTmp].

tmpl should be a string in the GLib file name encoding containing a sequence of six 'X' characters, and containing no directory components. If it is null, a default template is used.

`ioPriority`	the [I/O priority][io-priority] of the request
`cancellable`	optional #GCancellable object, null to ignore
`callback`	a #GAsyncReadyCallback to call when the request is done
