In variadic functions we still do the cast. In POSIX, it's not necessary, since NULL is required to be of type 'void *', and 'void *' is guaranteed to have the same alignment and representation as 'char *'. However, since ISO C still doesn't mandate that, and moreover they're doing dubious stuff by adding nullptr, let's be on the cautious side. Also, C++ requires that NULL is _not_ 'void *', but either plain 0 or some magic stuff. Signed-off-by: Alejandro Colomar <alx@kernel.org>
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.
