struct.link.isgroup

Syntax

b := struct.link.isgroup(p,s<,slot>)

Check if the group s is associated with the link and return true if a match is found in any slot. The check for s will only occur in slot, if provided.

A group index or slot index may be used for the arguments s or slot, respectively. Indices operate more efficiently than strings*.

Returns:

b - true if the group was found

Arguments:

p - link pointer

s - the group name or index*

slot - the slot name or index* (restricts removal of s to that slot)

Note

*Use the group.find and group.find.slot intrinsics to obtain group and slot indices, respectively, and for further information.

Use of the group logic is described in Groups.
