[comp.sys.mac.hypercard] synchronization of pictures and xcmds

biling@ucscd.UCSC.EDU (Doug Rosener) (03/10/89)

I am writing a stack which will display a picture, and then perform an
xcmd immediately after the picture appears.  There can be no delay between
the xcmd execution and the picture display.

SInce I didn't write the xcmd, and have no documentation, is there a way
to make sure that there will be no delays due to interrrupts and other 
overhead.  For an average system, what is the typical time to service
the 1/60 sec interrupt?

Thanks,
