| | | | | | value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.

* - General changes:mestre2016-03-071-2/+2
| | | | | | | | | | | | - 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
* Some basic code maintenance in games/tb2016-01-071-3/+2
| | | | | | | | | | - 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 cleanup and sorting on header sectionmestre2016-01-0411-34/+44
| | | | | OK tb@ and he also pointed out that for consistency with rest of the tree we should include termios.h instead of sys/ttydefaults.h, where applicable
* Set as __dead a few more functions, that don't return, on games/mestre2015-12-261-2/+2
| | | | With precious tip, help and also OK from tb@
* Declare usage() functions as __dead void, if they don't return, on games section.mestre2015-12-251-2/+2
| | | | | | 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@

| | | | | | | LOGNAME -> USER -> getlogin() -> ??? fallback in the score file, as requested by tedu@ Man page bits adapted from jmc@'s tweaks to snake.6
* Move scorefile to $HOME. The nice implementation of the score filetb2015-11-295-56/+29
| | | | | depends on getpwuid(), so add "getpw" to the rest of the required pledges: "stdio rpath wpath cpath tty".
* In 1995, all of the games were setuid games. At end of 1996, I took them allderaadt2015-11-241-2/+1
| | | | | | | | | to setgid games, and we started wittling them down. Nearly 10 years later I am removing all setgid from the games. If any of these have score files they are now broken, and I hope various folk repair them. I have argued for years (and received pushback...) that the score file features must be removed, or rewritten to use private files, because setgid is the wrong tool. ok tedu
* Improve robots(6) by using timespec*() functions, replacing gettimeofday()rzalamena2015-08-264-22/+19
| | | | | | | with clock_gettime(MONOTONIC) to avoid clock changes and replacing poll() with ppoll() to deal better with timespec. ok guenther@.
