Functions

Global functions can be registered with Lua Bridge as well. These functions don't need to have the same signature as lua_CFunction; as Lua Bridge will generate the required glue code. Functions can be exposed with the addFunction function. This function takes two arguments. The first one is the Lua-side name of the function, and the second is a pointer to the function. The following code demonstrates how to do this:

int bar() {    return 2;}getGlobalNamespace(L)    .beginNamespace("foo")        .addFunction("bar", bar)    .endNamespace()

It is also possible to register functions written against the Lua C API that match the signature of lua_CFunction. You will most often do this if you need to port some legacy code over, in order to use Lua Bridge. ...
