Hello Mtk I noticed "nonzero" needs a hyphen "non-zero", could that be changed please? Also there is a word "nonempty" which isn't a word, and isn't needed I feel :- "Allocation of nonempty argz vectors is done using malloc(3), so that free(3) can be used to dispose of them again." May I ask if that be changed to :- "Allocation of argz vectors is done using malloc(3), so that free(3) can be used to dispose of them again." https://man7.org/linux/man-pages/man3/argz_create.3.html Kind regards Jonny
