pdmdrv.h@ 88054

Last change on this file since 88054 was 87761, checked in by vboxsync, 4 years ago
VMM/DrvHlp: Changed the unused (at least internally) pfnTMTimerCreate interface to pfnTimerCreate and made it return a 'handle'. More helpers is required here if someone really wants to use timers in drivers. bugref:9943
