Joining a caucus

A caucus does not exist until the first member joins the caucus, when the TStandardCaucusMember constructor starts a caucus that runs on the host you specify with the service reference parameter. It might take a little longer for the first member to join a caucus than for subsequent members to join.

In addition to locating the proper caucus and adding the member to the caucus, the TStandardCaucusMember constructor also automatically issues a zero-byte join message to all caucus members (including the originator).

To join a caucus:

1. Instantiate a service reference to the caucus you want to join.
   
2. Construct a TStandardCaucusMember object using the service reference.
   

In this example, caucusText is the name of the caucus the client is joining, and hostText is the name of the host machine on which the caucus runs. For more information about constructing service reference objects, refer to the "Communications access" chapter of OS Services.
