.SH DESCRIPTION
.sp
.LP
When first called, \fBgetacdir()\fR provides information about the first audit
directory in the \fBaudit_control\fR file. Thereafter, it returns the next
directory in the file. Successive calls list all the directories listed in
\fBaudit_control\fR(4) The \fIlen\fR argument specifies the length of the
buffer \fIdir\fR. On return, \fIdir\fR points to the directory entry.
.sp
.LP
The \fBgetacmin()\fR function reads the minimum value from the
\fBaudit_control\fR file and returns the value in \fImin_val\fR. The minimum
value specifies how full the file system to which the audit files are being
written can get before the script \fBaudit_warn\fR(1M) is invoked.
.sp
.LP
The \fBgetacflg()\fR function reads the system audit value from the
\fBaudit_control\fR file and returns the value in \fIauditstring\fR. The
\fIlen\fR argument specifies the length of the buffer \fIauditstring\fR.
.sp
.LP
The \fBgetacna()\fR function reads the system audit value for non-attributable
audit events from the \fBaudit_control\fR file and returns the value in
\fIauditstring\fR. The \fIlen\fR argument specifies the length of the buffer
\fIauditstring\fR. Non-attributable events are events that cannot be attributed
to an individual user. The \fBinetd\fR(1M) utility and several other daemons
record non-attributable events.
.sp
.LP
The \fBsetac()\fR function rewinds the \fBaudit_control\fR file to allow
repeated searches.
.sp
.LP
The \fBendac()\fR function closes the \fBaudit_control\fR file when processing
is complete.
