gr_passwd  

Encrypted password. This field is not supported.

gr_gid

gr_mem  

List of group members.

CONFORMANCE

UNIX 98, with exceptions.

PORTING ISSUES

On Windows NT/2000/XP/2003/Vista, the structure is filled with information from the SAM database. Refer to Users and Groups in the Windows Concepts chapter of the MKS Toolkit UNIX to Windows Porting Guide.

Windows NT/2000/XP/2003/Vista security allows only administrators and members of a group to enumerate the members of a group. Therefor, the gr_mem field of the group structure may be empty on a successful return.
