iuplua_open
Initializes the Lua Binding. This function should be called by the host program before running any Lua functions, but it is important to call it after IupOpen.
It is also allowed to call iuplua_open without calling IupOpen. Then IupOpen will be internally called. This enable you to dynamically load IUP using Lua 5 "require". This is also valid for all the additional controls when IUP is dynamically loaded. To call IupClose in this way you must call iuplua_close.
Parameters/Return
int iuplua_open(void); [in C for Lua 3] int iuplua_open(lua_State *L); [in C for Lua 5] [There is no equivalent in Lua]
Returns: 0 (the number of elements in the stack).
