[comp.sys.mac.programmer] Vertical Retraces

tarr-michael@CS.Yale.EDU (michael tarr) (07/21/90)

Anyone out there have some Think C code to find out when a monitor
begins its vertical retrace (on the old macs tickcount did it). With all
the monitor possibilities it is a bit tricky -- I guess I would use the
VBL manager, but I am mystified by this part of IM.
