* When system calls indicate an error they return -1, not some arbitraryderaadt2019-06-282-5/+5
| | | | | | 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.

| | | | | | | 'i' shadows the local loop indexing variable of scr_update(), so no need to rename it. No binary change on amd64. ok millert
* When eliding a row, clear the invisible row zero, so that no columnstb2016-06-101-1/+2
| | | | | | | can become unusable during game play. Same fix was made in NetBSD's tetris.c -r1.31 by Christos Zoulas almost exactly a year ago. ok tedu
* Prefer fseek(3) over rewind(3) since the latter although it also calls fseekmestre2016-03-161-2/+3
| | | | | | | then additionally it calls clearerr(3) deliberately but we want to catch any error that may happen and this way we couldn't catch it OK tb@
* - General changes:mestre2016-03-071-2/+3
| | | | | | | | | | | | - 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/+3
| | | | | | | | | | - 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 sectionmestre2016-01-045-22/+12
| | | | | 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
* About 13 years ago when the idiom srandom(time()), and sometimesmestre2016-01-031-5/+4
| | | | | | | | | | | | srandom(time()+getpid()), was changed by srandomdev(), but #include <time.h> 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@
