wpRestoreState - Example Code

In this example, wpRestoreState is overridden to restore data from the OS2.INI file.

SOM_Scope void   SOMLINK UserSetTitle(nbk *somSelf,
                                      PSZ pszNewTitle)
{
    nbkData *somThis = nbkGetData(somSelf);
    nbkMethodDebug("nbk","UserSetTitle");

   strcpy ( _title, pszNewTitle );
}
/*
 *    Override of  wpRestoreState method to restore our data
 *    from the OS2.INI file.
 */

{
    BOOL fSuccess;
    ULONG ulCount;
    CHAR buf[40];

    nbkData *somThis = nbkGetData(somSelf);
    nbkMethodDebug("nbk","wpRestoreState");
