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.
