Exactly what cuserid() does is poorly defined (e.g., some systems use the
effective uid, like Linux, while others like System V use the real uid).
Thus, you can't trust what it does. It's certainly not portable (The
cuserid function was included in the 1988 version of POSIX, but removed
from the 1990 version). Also, if passed a non-null parameter, there's a
risk of a buffer overflow if the passed-in buffer is not at least L_cuserid
characters long (CWE-120). Use getpwuid(geteuid()) and extract the desired
information instead.
