LIBRARY

SYNOPSIS
  #include <apar_types.h>
  #include <sys/class.h>

  class_change(class_apar_handle_t handle,
  char *class_name,
  struct resource_limits *limits);

PARAMETERS
  handle
      The partition descriptor returned by class_open().

  class_name
      The name of the class to change.

  limits
      The input is the new resource limits, the output is the resources
      available.

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.
