Excellent explanation. Thank you.
Indeed. Thanks to gvb.
I'd just like to add that you also never know if SZ_1M is 1024*1024 or 1000*1000.
I do like this (from the email link): (31 * 1024 * 1024). And it appears not to give Wolfgang indigestion :)
It is probably the preferred form in many cases, line length permitting :-) "31 << 20" is a bit shorter, but it's just a personal
s/3// ;-)
preference, not something I consider better in any way.
Best regards,
Wolfgang Denk
Another objection: Company A makes their favorite SZ_* defines but Company B defines them as SIZE_* but Company C defines them as...
...and we end up with the same mess as INT32 vs. WORD vs. int32_t defines (C99 tackled that, finally, but not all the mess has been cleaned up yet, 10 years later).
Best regards, gvb
