pairs

In Lua, using the C interface, given a table, how do I iterate through the table's key/value pairs?

Also, if some table table members are added using arrays, do I need a separate loop to iterate through those as well or is there a single way to iterate though those members at the same time as the key/value pairs?

I am wondering if it is possible therefore, to add new (Lua) methods to the C++ object table so that I can achieve the effect of adding new methods to the C++ class… >>> More
