The partition descriptor returned by class_open(). 

class_name
The name of the class to change.

DESCRIPTION

This system call changes the limits of the resources that an existing class is allowed to use.  If the value of percent would cause the total resource percentage of all classes to exceed 100 per cent, then the call will fail.  On output, the structure contains the remaining resource percentages available. 

Specify CLASS_RESOURCE_NO_CHANGE for all resources that are to remain unchanged if  you only need to change some resources. 

Specify  CLASS_RESOURCE_SCHED_DISABLED for the target limit of any resource that is not needed.
