Why?
The interface has just a simple local (process) ref count while the CorePalette being a FusionObject has a reference counter adding all processes' references to the object as well as the 'global' or 'anonymous' references that are used for inter-shared-object dependencies (pointer from CoreSurface to CorePalette). -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" _______________________________________________ directfb-users mailing list directfb-users@directfb.org http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-users
