The delay functions in Turbo C and Turbo Pascal use the DOS call to get
DOs's time. This is updated at about 18.2 Hz, so the clock is only accurate
to about 0.05 second resolution.

The TC and TP delay functions use a delay loop which is calibrated on the first call (TC) or at program startup (TP). It allows delays to millisecond precision with a fair amount of accuracy, provided you don't have some other code stealing time (particularly during the one clock-tick calibration period). -- UUCP: {ucbvax,harvard}!cs.cmu.edu!ralf -=- 412-268-3053 (school) -=- FAX: ask ARPA: ralf@cs.cmu.edu BIT: ralf%cs.cmu.edu@CMUCCVMA FIDO: Ralf Brown 1:129/46 "How to Prove It" by Dana Angluin Disclaimer?
