| TEST ITEMS: |
| 1. Check to see if getgroups(-1, gidset) fails and sets errno to EINVAL |
| 2. Check to see if getgroups(0, gidset) does not return -1 and gidset is |
| not modified. |
| 3. Check to see if getgroups(x, gigset) fails and sets errno to EINVAL, |
| where x is one less then what is returned by getgroups(0, gidset). |
| 4. Check to see if getgroups() succeeds and gidset contains |
| group id returned from getgid(). |
