struct.link.isgroup

Syntax

Check if the group s is associated with the structural link. Will return true if a match is found in any slot. If the optional third argument slot is provided, then it will only check that slot.

A group pointer and/or a slot index may be used for increased efficiency. See the group.find and group.find.slot functions.

Note that this will travel up the data hierarchy, as described in Group Heirarchies.

Returns:

b - true if the group was found in that link

Arguments:

p - a pointer to a structural link

s - a group name

slot - an optional slot specification. If not provided, the check will occur on all slots that have been assigned to the link.
