.SH DESCRIPTION
.LP
These functions document the programming interface for obtaining entries from
the \fBaudit_event\fR(4) file. The \fBgetauevent()\fR, \fBgetauevnam()\fR,
\fBgetauevnum()\fR, \fBgetauevent()\fR, \fBgetauevnam()\fR, and
\fBgetauevnum()\fR functions each return a pointer to an \fBaudit_event\fR
structure.
.sp
.LP
The \fBgetauevent()\fR and \fBgetauevent_r()\fR functions enumerate
\fBaudit_event\fR entries. Successive calls to these functions return either
successive \fBaudit_event\fR entries or \fINULL\fR.
.sp
.LP
The \fBgetauevnam()\fR and \fBgetauevnam_r()\fR functions search for an
\fBaudit_event\fR entry with \fIevent_name\fR.
.sp
.LP
The \fBgetauevnum()\fR and \fBgetauevnum_r()\fR functions search for an
\fBaudit_event\fR entry with \fIevent_number\fR.
.sp
.LP
The \fBgetauevnonam()\fR function searches for an \fBaudit_event\fR entry with
\fIevent_name\fR and returns the corresponding event number.
.sp
.LP
The \fBsetauevent()\fR function ``rewinds'' to the beginning of the enumeration
of \fBaudit_event\fR entries. Calls to \fBgetauevnam()\fR,
\fBgetauevnum()\fR, \fBgetauevnonum()\fR, \fBgetauevnam_r()\fR, or
\fBgetauevnum_r()\fR can leave the enumeration in an indeterminate state. The
\fBsetauevent()\fR function should be called before the first call to
\fBgetauevent()\fR or \fBgetauevent_r()\fR.
.sp
.LP
The \fBendauevent()\fR function can be called to indicate that
\fBaudit_event\fR processing is complete. The system can then close any open
\fBaudit_event\fR file, deallocate storage, and so forth.
.sp
.LP
The \fBgetauevent_r()\fR, \fBgetauevnam_r()\fR, and \fBgetauevnum_r()\fR
functions each take an argument \fIe\fR, which is a pointer to an
\fBau_event_ent_t\fR. This pointer is returned on a successful function call.
To assure there is enough space for the information returned, the applications
programmer should be sure to allocate \fBAU_EVENT_NAME_MAX\fR and
\fBAU_EVENT_DESC_MAX\fR bytes for the \fBae_name\fR and \fBac_desc\fR elements
of the \fBau_event_ent_t\fR data structure.
.sp
.LP
The internal representation of an \fBaudit_event\fR entry is an
\fBau_event_ent\fR structure defined in <\fBbsm/libbsm.h\fR> with the following
members:
.sp
.in +2
.nf
au_event_t ae_number
char *ae_name;
char *ae_desc*;
au_class_t ae_class;
.fi
.in -2
.SH RETURN VALUES
.LP
The \fBgetauevent()\fR, \fBgetauevnam()\fR, \fBgetauevnum()\fR,
\fBgetauevent_r()\fR, \fBgetauevnam_r()\fR, and \fBgetauevnum_r()\fR functions
return a pointer to a \fBau_event_ent\fR structure if the requested entry is
successfully located. Otherwise they return \fINULL\fR.
.sp
.LP
The \fBgetauevnonam()\fR function returns an event number of type
\fBau_event_t\fR if it successfully enumerates an entry. Otherwise it returns
\fINULL\fR, indicating it could not find the requested event name.

.LP
The \fBgetauevent()\fR, \fBgetauevnam()\fR, and \fBgetauevnum()\fR functions
are Unsafe. The equivalent functions \fBgetauevent_r()\fR,
\fBgetauevnam_r()\fR, and \fBgetauevnum_r()\fR provide the same functionality
and an MT-Safe function call interface.

.SH NOTES
.LP
All information for the \fBgetauevent()\fR, \fBgetauevnam()\fR, and
\fBgetauevnum()\fR functions is contained in a static area, so it must be
copied if it is to be saved.
