Set group properties ( groupID ; name ; owner {; members} ) -> Function result

Parameter	Type	Description
groupID	Longint	Unique ID number of group, -1 for adding a group
		Unique ID number of added group (if any)
name	String	New group name
owner	Longint	User ID number of new group owner (Binary databases only)

Description

Set group properties enables you to change and update the properties of an existing group whose unique group ID number you pass in groupID, or to add a new group.

To change the properties of an existing group, you must pass a valid group ID number returned by the command GET GROUP LIST.

To add a new group, pass -1 in groupID (see also notes below for binary databases).

After the call, if the group is successfully added, its unique ID number is returned in groupID.

If you do not pass -1, -2 or a valid group ID number in groupID, Set group properties does nothing.

Pass the new name of the group in the name parameter.

(Binary databases only) Pass the ID number of the new owner of the group in the owner parameter. This parameter is ignored in project databases.

If you do not want to change all the properties of the group (besides the members, see below), first call GET GROUP PROPERTIES and pass the returned values for the properties you want to leave unchanged.

If you do not pass the optional members parameter, the current member list of the group is left unchanged. If you do not pass members while adding a group, the group will have no members.

If you pass the optional members parameter, you change the whole member list for the group. Before the call, you must populate the array members with the unique ID numbers of the users and groups the group will get as members.

To remove all the members from a group, pass an empty members array.

Notes for binary databases

Group and user ID values depend on their creator (Designer, Administrator, or affiliated group owner). For more information, please refer to the User and group ID ranges paragraph. To create a group affiliated with the Designer, pass -1 in groupID. To create a group affiliated with the Administrator, pass -2 in groupID.
The group owner is not automatically set as a member of the group that he or she owns. It is up to you to include the group owner in the group, using the members parameter.

Error management

If you do not have the proper access privileges for calling Set group properties or if the Password system is already accessed by another process, an access privilege error is generated. You can catch this error with an error-handling method installed using ON ERR CALL.
