This function is like strlcpy(3), but returns -1 on truncation, which makes it much easier to test. strlcpy(3) is useful in two cases: - We don't care if the output is truncated. strlcpy(3) is fine for those, and the return value can be ignored. - Truncation is bad. In that case, we just want to signal truncation, and the length of the original string is quite useless. Return the length iff no truncation so that we can use it if necessary. This simplifies the definition of the STRLCPY() macro. 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.
