Hello

In /usr/share/Performer/src/pguide/libpr/C

I found: hlcube.c

In hlcube.c ...

There is this code snip:

        /*etc*/

    win = pfNewWin(NULL);
    pfWinOriginSize(win, 0, 0, 500, 500);
    pfWinName(win, "Performer cubes");
    pfWinType(win, PFWIN_TYPE_X);
    pfOpenWin(win);

    frust = pfNewFrust(NULL);
    pfMakeSimpleFrust(frust, 45.0f);
    pfFrustNearFar(frust, 1.0f, 100.0f);
    pfApplyFrust(frust);
    pfDelete(frust);

        /*etc*/

Could somone tell me why one can delete the "frust" right
after creating it and setting its attributes?
What is gained?
Why is this allowed?

Thanks,
Tom
