* Add static keywords to variables and functions where possible in games/.ed2011-11-051-17/+18
| | | | | This allows us to detect unused functions and variables and allows the compiler to do a better job at optimisation.
* grdc(6): de-obfuscate the timekeeping of now/delayuqs2010-08-031-6/+8
| | | | | | | | | - 'now' only contains current time readings - delay is only used as parameter to nanosleep - prev_sec contains the time_t of the previous loop iteration Submitted by: bde MFC after: 2 weeks
* grdc(6): Partial backout of r210755uqs2010-08-031-18/+24
| | | | | | | | | | | | | | | | | The previous revision was flawed in numerous ways: - the if condition would depend on garbage stack values - grdc(6) would loop n times, not n seconds. This only makes a difference if it takes more than 1 second to recalculate/redraw the display. - style(9) violations The following change adds argument checking and tracks the elapsed time between loops explicitly and will exit after roughly n seconds. While here sort headers and remove bogus #ifndef Submitted by: bde MFC after: 2 weeks
* grdc(6): fix timekeeping for user-supplied value nuqs2010-08-021-18/+15
| | | | | | | | | - Keep timespec 'now' and 'delay' separate to avoid confusion - Increase user-supplied n to run _at least_ n seconds, not max n PR: bin/149130 (based on) Submitted by: Andy Farkas MFC after: 2 weeks

* Improve time precision for grdc(6):delphij2010-02-101-2/+15
| | | | | | | | | | | | | | | | | | | Traditionally, grdc would obtain time through time(3) which in turn gets only the second part of clock (CLOCK_SECOND), and sleep for 1 second after each screen refresh. This approach would have two problems. First, we are not guaranteed to be waken up at the beginning of a whole second, which will typically exhibit as a "lag" on second number. Second, because we sleep for whole second, and the refresh process would take some time, the error would accumulate from time to time, making the lag variable. Make grdc(6) to use time(3) to get time only at the beginning, and sample time in CLOCK_REALTIME_FAST granularity after refreshing, and use the nanosecond part to caculate how much time we want to sleep.
