Control Code Reference

The Cluster API defines a small set of control code functions—one for each cluster object—as "generic" interfaces to a wide range of cluster operations. Control codes—32 bit values used as function parameters—determine the kind of operation a control code function will perform. Together, the control code functions and the control codes support nearly every kind of cluster functionality.

Refer to the following sections:

For reference information on the control code functions and their related control codes, see Control Code Functions.

For background information on the control codes, including how to create user-defined control codes, see Using Control Codes.
