CLUSCTL_RESOURCE_VM_CANCEL_MIGRATION control code

Cancels an ongoing live migration of a virtual machine (VM). The migration can be canceled only if the migration is in the "Setup" (MigrationState is 1) or "Data Transfer" (MigrationState is 2) states and the resource control is called on the source node of the live migration. Applications use this control code as a parameter to the ClusterResourceControl function, and resource DLLs receive the control code as a parameter to the ResourceControl callback function.

ClusterResourceControl( hResource,           // resource handle
                        hHostNode,           // optional node handle
                        CLUSCTL_RESOURCE_VM_CANCEL_MIGRATION, 
                        NULL,                // input buffer (not used)
                        0,                   // input buffer size (not used)
                        NULL,                // output buffer (not used)
                        0,                   // output buffer size (not used)
                        NULL );              // resulting data size (not used)
