grdc(6): implement timeout with alarm(3)

2020-06-06T17:03:16Z

grdc(6) has an optional argument indicating a timeout in seconds. For example, one could do: $ grdc 60 to to tell grdc(6) to run for sixty seconds and then exit gracefully. As implemented, however, the timeout may occur too early or too late if the system clock is reset with settimeofday(2). To avoid this problem we can instead use alarm(3) and a signal handler to implement the timeout. alarm(3) is unaffected by settimeofday(2).

grdc(6): miscellaneous style(9)

- Sort includes alphabetically - Sort function prototypes alphabetically - Add missing whitespace after commas - Remove extra whitespace after commas - Add missing whitespace between binary operators - Add missing whitespace between reserved words and parens, i.e. fix "if(" - Add missing __dead to usage() definition

When system calls indicate an error they return -1, not some arbitrary

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.

allow q to exit the program.

reduce pledge(2) to "stdio tty" after ncurses initialization.

OK tb@

The code can be simplified by using clock_gettime(2)'s CLOCK_REALTIME

instead of gettimeofday(2). From Scott Cheloha, ok jca

Convert fprintf(stderr, ...) to errx/warnx (with slight change of output).

From Scott Cheloha

- 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

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@
