.Sh NAME
.Nm audit_submit
.Nd "general purpose audit record submission"
.Sh LIBRARY
.Lb libbsm
.Sh SYNOPSIS
.In bsm/libbsm.h
.Ft int
.Fo audit_submit
.Fa "short au_event" "au_id_t auid" "char status"
.Fa "int reterr" "const char * restrict format" ...
.Fc
.Sh DESCRIPTION
The
.Fn audit_submit
function provides a generic programming interface for audit record submission.
This audit record will contain a header, subject token, an optional text token,
return token, and a trailer.
The header will contain the event class specified by
.Fa au_event .
The subject token will be generated based on
.Fa auid .
The return token is dependent on the
.Fa status
and
.Fa reterr
arguments; unlike the argument to
.Xr au_to_return ,
.Fa reterr
should be a local rather than BSM error number.
Optionally, a text token will be created as a part of this record.
.Pp
Text token output is under the control of a
.Fa format
string that specifies how subsequent arguments (or arguments accessed via the
variable-length argument facilities of
.Xr stdarg 3 )
are converted for output.
If
.Fa format
is
.Dv NULL ,
then no text token is created in the audit record.
.Pp
It should be noted that
.Fn audit_submit
assumes that
.Xr setaudit 2 ,
or
.Xr setaudit_addr 2
has already been called.
As a direct result, the terminal ID for the
subject will be retrieved from the kernel via
.Xr getaudit 2 ,
or
.Xr getaudit_addr 2 .
