I have C++ function
void f(Foo **arg);
that I'm exposing to Lua using toLua.
tolua produces .cpp file that expects Foo *, not Foo**.
Generated file looks like
....
!tolua_isusertype(tolua_S,5,"Foo",0,&tolua_err) ||
....
and then
arg = (Foo *)tolua_tousertype(...)
f(&arg);
C++ function is designed to store something into pointer "arg". But
tolua fails to understand it.
Moreover, if I am using triple pointer:
void f(Foo ***arg);
tolua generates something like that:
Foo**arg = ((Foo*) tolua_tousertype(...);
that could not compile due to type mismatch in left hand side and
right hand side.
Or maybe I am doing something wrong? Thanks in advance.
