These overloaded macros allow passing either a const or a non-const endp, and will call the appropriate function. This kind of const overloading has prior art in C23's string functions, such as memchr(3). Martin suggested using an artificial function pointer in _Generic(3); it allows switching on various types at the same time. Also add a comment referring to liba2i's PDF manual for documentation.

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.
