Well, here's what I have in my manual...  cuserid(3S)

#include <stdio.h>
char *cuserid(s)
char *s;

Generate a string representation of the login name of the owner of the
current process.  If s is a NULL pointer, then cuserid will allocate space
for the login name.  If not, then cuserid expects s to be an array of at
least L_cuserid characters.  (Defined in stdio.h)  If an error, a null
pointer is returned if called with a null pointer, else s[0]='\0'

Something could be easily make with getpwuid(getuid()) to return the
desired results.
