It wraps strlcpy(3bsd) so that it performs some steps that one might forget, or might be prone to accidents: - It calculates the size of the destination buffer, and makes sure it's an array (otherwise, using sizeof(dst) would be very bad). - It calculates if there's truncation, returning an easy-to-use value. BTW, this macro doesn't have any issues of double evaluation, because sizeof() doesn't evaluate its argument (unless it's a VLA, but then the static_assert(3) within SIZEOF_ARRAY() makes sure VLAs are not allowed).

shadow-utils
Introduction
The shadow-utils package includes the necessary programs for converting UNIX password files to the shadow password format, plus programs for managing user and group accounts. The pwconv command converts passwords to the shadow password format. The pwunconv command unconverts shadow passwords and generates a passwd file (a standard UNIX password file). The pwck command checks the integrity of password and shadow files. The lastlog command prints out the last login times for all users. The useradd, userdel, and usermod commands are used for managing user accounts. The groupadd, groupdel, and groupmod commands are used for managing group accounts.
