use getuid and then look that up in the /etc/passwd file. Not hard if you
know what you're doing.

if ((fpIn = fopen ("/etc/passwd", "r")) == NULL)
{
   // error
}
while (!feof(fpIn))
{
   char * szTemp = fgets (fpIn) ;
   //see if user's id is in the string you just read from the file
   // strstr() if I recall correctly
}
close (fpIn) ;
