The getauclassent() function and getauclassnam() each return an
audit_class entry.

The getauclassnam() function searches for an audit_class entry with a
given class name name.

The getauclassent() function enumerates audit_class entries. Successive
calls to getauclassent() return either successive audit_class entries or

The setauclass() function ``rewinds'' to the beginning of the enumeration
of audit_class entries. Calls to getauclassnam() may leave the
enumeration in an indeterminate state, so setauclass() should be called
before the first getauclassent().

The endauclass() may be called to indicate that audit_class processing is
complete; the system may then close any open audit_class file, deallocate
storage, and so forth.

The getauclassent_r() and getauclassnam_r() functions both return a
pointer to an audit_class entry as do their similarly named counterparts.
They each take an additional argument, a pointer to pre-allocated space
for an au_class_ent_t, which is returned if the call is successful. To
assure there is enough space for the information returned, the
applications programmer should be sure to allocate AU_CLASS_NAME_MAX and
AU_CLASS_DESC_MAX bytes for the ac_name and ac_desc members of the
au_class_ent_t data structure.

The internal representation of an audit_class entry is an au_class_ent
structure defined in <bsm/libbsm.h> with the following members:

char *ac_name;
au_class_t ac_class;
char *ac_desc;


The getauclassnam() and getauclassnam_r() functions return a pointer to a
au_class_ent structure if they successfully locate the requested entry.
Otherwise they return NULL.

The getauclassent() and getauclassent_r() functions return a pointer to a
au_class_ent structure if they successfully enumerate an entry. Otherwise
they return NULL, indicating the end of the enumeration.

See attributes(7) for descriptions of the following attributes:

|MT-Level | MT-Safe with exceptions. |

All of the functions described on this man-page are MT-Safe except
getauclassent() and getauclassnam, which are Unsafe. The
getauclassent_r() and getauclassnam_r() functions have the same
functionality as the Unsafe functions, but have a slightly different
function call interface to make them MT-Safe.
