IUP - Portable User Interface


Initializes the IUP toolkit. Must be called before any other IUP function.


int IupOpen(void); [in C]
[There is no equivalent in Lua]

This function returns IUP_ERROR or IUP_NOERROR.


The IupOpen function in the Windows driver initializes OLE through the function OleInitialize; IupClose calls OleUninitialize.

The toolkit's initialization depends on several platform-dependent environment variables.

For a more detailed explanation on the system control, please refer to Guide / System Control.

Lua BindingĀ 

Lua: This function must be called by the host program and before the Binding Lua initialization function, iuplua_open.
