Take a look at the code in modules/wxluadebug/src/wxldebug.cpp
int wxLuaDebugData::EnumerateTable(const wxLuaState& wxlState_, int
tableRef, int nIndex, wxArrayInt& references)
switch (lua_type(L, -2))
case LUA_TFUNCTION:
if (lua_iscfunction(L, -2))
name.Printf(wxT("%p"), lua_tocfunction(L, -2));
else
name.Printf(wxT("%p"), lua_topointer(L, -2));
break;
----------------
You could do
lua_getglobal(L, "myfunction");
if (lua_isfunction(L, -1))
{
lua_CFunction* fn = lua_tocfunction(L, -1);
lua_pop(L, -1);
if (fn)
fn(L); // I forget how to call a pointer fn?
}
else if (!lua_isnil(L, -1))
lua_pop(-1);
