Deletes a class.
Workload Manager Library (libwlm.a)
#include <sys/wlm.h>
int wlm_delete_class ( wlmargs)
struct wlm_args *wlmargs;
The wlm_delete_class subroutine deletes an existing superclass or subclass. A superclass cannot be deleted if it still has subclasses other than Default and Shared defined.
The caller must have root authority to delete a superclass and must have administrator authority on a superclass to delete a subclass of the superclass.
| wlmargs | Specifies the address of the struct wlm_args data structure containing the information about the class to be deleted. |
The following fields of the wlm_args structure and the embedded
substructures need to be provided:
| versflags | Needs to be initialized with WLM_VERSION. |
| confdir | Specifies the name of the WLM configuration the target class belongs
to. It must be either the name of a valid subdirectory of
/etc/wlm or an empty string (starting with '\0').
If the name is a valid subdirectory, the relevant class description files in the specified configuration are modified. If the name is a null string, no description files are updated. The class is removed from the kernel WLM data structures. |
| name | Specifies the name of the superclass or of the subclass to be deleted. If this is a subclass name, it must be of the form super_name.sub_name. There is no default for this field. |
All the other fields can be left uninitialized for this call.
Upon successful completion, the wlm_delete_class subroutine returns a value of 0. If the wlm_delete_class subroutine is unsuccessful, a non-0 value is returned.
