syscall of the day: getrusage Anonymous 03/20/26(Fri)10:26:55 No.108414057

previous: >>108406971
#define __NR_getrusage            98
https://man7.org/linux/man-pages/man2/getrusage.2.html

tl;dr:
get an account of process resource usage

it's interesting that this accounts for all children and their descendants. that's a lot of bookkeeping under the hood. i might have to go look into the source for this one, because wow.
this is another syscall with _GNU_SOURCE-gated functionality
>The _GNU_SOURCE feature test macro must be defined (before including any header file) in order to obtain the definition of this constant from <sys/resource.h>.
the fact that you have to define this at all, but especially before including any header file, always annoys me lol. really not a fan
:D

I can't see this being useful otherwise.

I'm glad to see yet another normal picture. I was so interested in the meme, I even clicked on the thread before seeing it's the greatest general we have on this board! Yes, I know how you pick pictures so this was likely a coincidence.
Also to add to your picture regarding too many else-ifs: There was some maniac who programmed is-even in C++ (I believe) solely with ifs and else-ifs. He still didn't hit the limit.
