Description Xavier Claessens 2014-05-21 15:19:45 UTC
Array support in generated code is totally wrong. See for example the generated code for g_application_run():

		public int Run(int argc, string argv) {
			int raw_ret = g_application_run(Handle, argc, GLib.Marshaller.StringToPtrGStrdup(argv));
			int ret = raw_ret;
			return ret;

That string will be interpreted by C code as an strv. The only thing it can do is a segfault. The proper generated API for that is "public int Run(string[] argv)" because the argc argument is already "contained" in the string[] type.

Branch reworking completely arrays: http://cgit.collabora.com/git/user/xclaesse/gtk-sharp.git/log/?h=array

I've been testing that to generate API from gio-sharp that uses gir xml https://github.com/xDarkice/gio-sharp.git. There are probably still some APIs that won't work, but for what I've seen it's all good :)

As mentioned by Xavier in bug #19838, the "array" branch linked above is not ready to be merged yet, as it doesn't take into account the implicit marshalling of arrays.

Xavier, for your information, you can also submit a pull request on https://github.com/mono/gtk-sharp
