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

       Create a new class.  The created class will be empty.  Use  class_add() to populate the class.  If the value of percent	causes	the  total
       percentage of all classes to exceed 100%, the call will fail and avail will contain the remaining  percentage available.

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

       Note that the calling process must have root access privileges.

RETURN VALUES

       The  operation  was  successfully  completed.   An  invalid  partition  handle  was specified.  The class_name is not an ASCII string.  The
       class_name already exists.  No space available in class_name.  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.

	      <?php
	      // define a class
	      class WidgetFactory
	      {
		var $oink = 'moo';
	      }

	      // create a new object
	      $WF = new WidgetFactory();

	      if (is_a($WF, 'WidgetFactory')) {
		echo "yes, $WF is still a WidgetFactory
";
	      }
	      ?>

       Example #2

	      Using the instanceof operator in PHP 5

	      <?php
