.TH AU_USER_MASK 3BSM "Mar 6, 2017"
.SH NAME
au_user_mask \- get user's binary preselection mask
.SH SYNOPSIS
.LP
.nf
\fBcc\fR [ \fIflag\fR... ] \fIfile\fR... \fB-lbsm\fR \fB -lsocket \fR \fB -lnsl \fR  [ \fIlibrary\fR... ]
#include <bsm/libbsm.h>

\fBint\fR \fBau_user_mask\fR(\fBchar *\fR\fIusername\fR, \fBau_mask_t *\fR\fImask_p\fR);
.fi

.SH DESCRIPTION
.LP
The \fBau_user_mask()\fR function reads the default, system wide audit classes,
combines them with the per-user audit classes, and updates the binary
preselection mask pointed to by \fImask_p\fR with the combined value.
.sp
.LP
The audit preselection mask is constructed as follows:
.sp
.in +2
.nf
success flags =
	(system default success flags + per-user always success flags)
		- per-user never success flags
failure flags =
	(system default failure flags + per-user always failure flags)
		- per-user never failure flags
.fi
.in -2
.sp
.LP
The \fBau_user_mask()\fR function fails only if the system wide audit flags
could not be retrieved.
.SH RETURN VALUES
.LP
Upon successful completion, \fBau_user_mask()\fR returns 0.

.SH NOTES
.LP
The \fBau_user_mask()\fR function should be called by programs like
\fBlogin\fR(1) which set a process's preselection mask with \fBsetaudit\fR(2).
\fBgetaudit\fR(2) should be used to obtain audit characteristics for the
current process.
.sp
.LP
If global zone auditing is set, a local zone cannot reduce the default
flags.
