Hi Arnold,
|
||||
in a process of fixing of strftime() in libraries on Atari ST I grabbed
|
||||
some pieces of code from your own strftime. When doing that it came
|
||||
to mind that your weeknumber() function compiles a little bit nicer
|
||||
in the following form:
|
||||
/*
|
||||
* firstweekday is 0 if starting in Sunday, non-zero if in Monday
|
||||
*/
|
||||
{
|
||||
return (timeptr->tm_yday - timeptr->tm_wday +
|
||||
(firstweekday ? (timeptr->tm_wday ? 8 : 1) : 7)) / 7;
|
||||
}
|
||||
How nicer it depends on a compiler, of course, but always a tiny bit.
|
||||
|
||||
Cheers,
|
||||
Michal
