This is great (in respect to a #freebsd IRC from 2021-07-02)! Are there plans to address 19:26 < RhodiumToad> and in fact sysconf(_SC_NPROCESSORS_ONLN) is implemented as sysctl hw.ncpu or 19:25 < RhodiumToad> on fbsd 13 on a 4-cpu box, cpuset -l 0-1 getconf _NPROCESSORS_ONLN returns 4 rather than 2 or even add a shallow usr.bin/nproc(1) that does only this operation, as in Linux? (Or ln(1) it and check out argv[0] to do so?) Having a "portable" thing would be great. --steffen | |Der Kragenbaer, The moon bear, |der holt sich munter he cheerfully and one by one |einen nach dem anderen runter wa.ks himself off |(By Robert Gernhardt)
