Set property of the owner.

<cMember>
Name of member object to be linked.

Logical true if successful, false otherwise. If the function returns

Description

The member object will be connected to the owner object via the 
specified set property.

When adding a user to a group, you must link the user to the group's 
GROUP_MEMBERS set in addition to linking the group to the user's 
GROUPS_I'M_IN set. The bi-directional connection is not automatic.

Let's say, for example, that you want to link a user object named DAVID 
to the group object EVERYONE. The operation will require two steps, the 
first to link EVERYONE to DAVID, and the second to link DAVID to 
EVERYONE.

The first step, linking DAVID to EVERYONE, makes the connection through 
DAVID's property GROUPS_I'M_IN. The code to do this is:

N_B_LINK('DAVID',         ;  // <cOwner>
         1,               ;  // <nType>
         "GROUPS_I'M_IN", ;  // <cProperty>
         'EVERYONE',      ;  // <cMember>
         2                )  // <nType>

The second step, linking EVERYONE to DAVID, makes the connection 
through GROUP_MEMBERS, a property of the group object EVERYONE. The 
code to do this is:

N_B_LINK('EVERYONE',      ;  // <cOwner>
         2,               ;  // <nType>
         'GROUP_MEMBERS', ;  // <cProperty>
         'DAVID',         ;  // <cMember>
         1                )  // <nType>

The properties used to forge the link must already exist or must be 
created with N_B_PRCREATE(). If a property does not exist, or if it is 
not a set property, or if either object does not exist, no action will 
be taken.

NetWare also expects that when you add a user to a group you will 
create and link the set property SECURITY_EQUALS.

Note  You must have write access in order to modify a property.

Commonly used set properties and object types are listed below.

                              entry in a
