IupShow
Displays a dialog in the current position, or changes a control VISIBLE attribute.
Parameters/Return
int IupShow(Ihandle *ih);ih: identifier of the interface element.
Returns: IUP_NOERROR if successful. If there was an error returns IUP_ERROR.

For dialogs, it is equivalent to call IupShowXY using IUP_CURRENT. See IupShowXY for more details.
For other controls, to call IupShow is the same as setting VISIBLE=YES.
