Another question:
I have a line of C code "PangoMatrix matrix = PANGO_MATRIX_INIT;" (http://library.gnome.org/devel/pango...h-Storage.html) and I want to convert it to Lua. The line will create a struct consisting 6 double variables.

I tried with "p_matrix = pango.PANGO_MATRIX_INIT". Lua interpretor did accept the form, but in fact p_matrix is still "nil". How do I solve the problem?

Added:
There seems a convenient utility: toLua (http://www.tecgraf.puc-rio.br/~celes/tolua/). But I can't build it on my Linux desktop.

Added 2:
I can build toLua now, but it seems not what I want.

Added 3:
Problem solved. The correct form is "p_matrix = pango.Matrix.INIT".

Added 4:
I am wrong. "p_matrix = pango.Matrix.INIT" is not correct.
