Changeset 75547 in vbox for trunk/src/VBox/Additions/common/VBoxGuest/lib

Message:

VBoxGuest: Added an IDC interface for faster HGCM calls (VBGL_IOCTL_IDC_HGCM_FAST_CALL, VbglR0HGCMFastCall). This expects the caller to construct a valid call and only concerns itself with issuing it to the host and waiting for the result to arrive. bugref:9172

Location:

• VBoxGuestR0LibHGCM.cpp (modified) (1 diff)
