wireguard-openbsd/games/random, branch master

- General changes:

2016-03-07T12:07:55Z

- Remove -? from getopt(3) options, but still keep (or add) -h where applicable - Replace hardcoded program strings by getprogname(3) - Specific changes: - atc(6): this used -? and -u for usage(), remove both from game and manpage - bcd(6): use __progname instead of getprogname(3), no need to include stdlib.h - hunt(6): replace fputs(3) by fprintf(3) OK tb@ after his suggestions

As per style(9), remove remaining lint-style comments from games/

2016-01-10T13:35:09Z

OK tb@

Some basic code maintenance in games/

2016-01-07T16:00:31Z

- in main() replace exit with return - drop some /* NOTREACHED */ lint comments along the way. - make more use of standard CFLAGS, esp. -Wimplicit-function-declaration - add and sort some headers when needed - add straightforward pledges to some programs used at compile time discussed with and ok mestre@

More headers removal and sorted the remaining alphabetically.

Most noticeable that were removed are sys/types.h which will be included from stdlib.h and in turn also brings along sys/cdefs.h. The other one is limits.h that was used with the old idiom (denom * random() / LONG_MAX), although it was only removed were applicable (some files still need that header). OK tb@

About 13 years ago when the idiom srandom(time()), and sometimes

2016-01-03T14:38:16Z

srandom(time()+getpid()), was changed by srandomdev(), but #include lived up until this day so remove it. Additionally, earlier than that, 18 years ago, random(6) was one of the first consumers of arc4random(3) family, and was pulling it from dev/rndvar.h but these days we pull it from stdlib.h, which is already done, so while here remove dev/rndvar.h also. "seems comprehensive to me" deraadt@ and OK tb@

Declare usage() functions as __dead void, if they don't return, on games section.

2015-12-25T20:59:09Z

Found another one in arithmetic(6) which also didn't return, and removed a function from number(6) which is not used anymore. OK tb@

replace setbuf with setvbuf, from Frederic Nowak

2015-11-04T21:22:10Z

Pledge "stdio" for simple games.

rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and

2009-10-27T23:59:19Z

unmaintainable). these days, people use source. these id's do not provide any benefit, and do hurt the small install media (the 33,000 line diff is essentially mechanical) ok with the idea millert, ok dms

Use arc4random_buf() when requesting more than a single word of output

2008-04-13T00:22:16Z

Use arc4random_uniform() when the desired random number upper bound is not a power of two ok deraadt@ millert@
