* Name: initgroups
*
* Description:
* The group database /etc/group is read to determine all groups of which
* user is a member. The additional group group is also added to this set,
* which is then used to set the supplementary group IDs of the calling
* process.
*
* Input Parameters:
* user - Name of the user to query the /etc/group database for.
* group - Additional gid to add to the list of group IDs.
*
* Returned Value:
* The initgroups() function returns zero if successful, and -1 in case of
* failure, in which case errno is set appropriately.
*
