Deleting a Class

Use the CIMClient deleteClass method to delete a class. Deleting a class removes the class, its subclasses, and all instances of the class; it does not delete any associations that refer to the deleted class.

Example — Deleting a Class

The example in Example 4–23 uses the deleteClass method to delete a class in the default namespace root\cimv2. This program takes four required string arguments (host name, class name, username, and password). The user running this program must specify the username and password for an account that has write permission to the root\cimv2namespace.
