Summary of CQS client requests

CQS client requests enable a client to access CQS or shared queues on coupling facility list structures. Your primary tool for writing a CQS client is the set of client request macros that CQS provides. You can use these requests to enable a client to access CQS or the shared queues on coupling facility list structures.
