class_change(3) 					     Library Functions Manual						   class_change(3)

NAME

       class_change - Change the alloted resources of an existing class.

LIBRARY

       Standard C Library (libclass.a)

SYNOPSIS

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

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

PARAMETERS

       The  partition  descriptor returned by class_open().  The name of the class to change.  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.

RETURN VALUES

       The operation was successfully completed.  An invalid partition handle was  specified.	The  class_name  is  not  an  ASCII  string.   The
       class_name  does  not  exist.   The  requested  percentage  not	is  not  in  the  range 0 - 100 or is not CLASS_RESOURCE_SCHED_DISABLED or
       CLASS_RESOURCE_SCHED_DISABLED.  Requested percentage not available. The struct resource_percent <xxx-available> (where xxx is an integer in
       the range 0-100 representing percentage) will contain  the maximum available percentage.
