Hello,
I'm having trouble with the syntax of Cairo.SvgSurface.for_stream() which
has the following signature in the vapi file:
[CCode (cheader_filename = "cairo.h")]
namespace Cairo {
⋮
public enum Status {
⋮
}
⋮
public static delegate Status WriteFunc (void* closure, uchar[] data);
⋮
[CCode (cname = "cairo_surface_t", cheader_filename = "cairo-svg.h")]
public class SvgSurface : Surface {
⋮
[CCode (cname = "cairo_svg_surface_create_for_stream")]
public SvgSurface.for_stream (WriteFunc write_func, void* closure,
double width_in_points, double height_in_points);
⋮
}
⋮
}
(where ⋮ means stuff deleted that I consider unrelated).
How should I call Cairo.SvgSurface.for_stream(). The following attempt
failed...
Cairo.Status my_write_func (void* closure, uchar[] data)
{
stderr.printf("%s", data);
return (Cairo.Status)0;
}
int main(string[] args)
{
⋮
var surface = new Cairo.SvgSurface.for_stream(my_write_func, null, 100,
100);
}
Thanks!
Dov
