TEST IDENTIFIER: getgroups01 : Getgroups system call critical test
|
||||
|
||||
PARENT DOCUMENT: ggrtds01: Getgroups system call test design spec
|
||||

||||
AUTHOR: Barrie Kletscher

|
||||
|
||||
CO-PILOT: Dave Baumgartner
|
||||
|
||||
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().
|
||||
|
||||
