new_tmp

Opens a file in the preferred directory for temporary files (as returned by get_tmp_dir) and returns a File and FileIOStream pointing to it.

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.

Unlike the other File constructors, this will return null if a temporary file could not be created.

Example: Temporary files:

public static int main (string[] args) {
	try {
		FileIOStream iostream;
		File file = File.new_tmp ("tpl-XXXXXX.txt", out iostream);
		print ("tmp file name: %s\n", file.get_path ());

		OutputStream ostream = iostream.output_stream;
		DataOutputStream dostream = new DataOutputStream (ostream);
		dostream.put_string ("my tmp data\n");
	} catch (Error e) {
		print ("Error: %s\n", e.message);
	}
	return 0;
}

valac --pkg gio-2.0 GLib.File.new_tmp.vala

Parameters:

tmpl	Template for the file name, as in open_tmp, or null for a default template
iostream	on return, a FileIOStream for the created file

Returns:

a new File. Free the returned object with unref.
