.Dt AU_FREE_TOKEN 3
|
|
.Os
|
|
.Sh NAME
|
|
.Nm au_free_token
|
|
.Nd "deallocate a token_t created by any of the au_to_*() BSM API functions"
|
|
.Sh LIBRARY
|
|
.Lb libbsm
|
|
.Sh SYNOPSIS
|
|
.In bsm/libbsm.h
|
|
.Ft void
|
|
.Fn au_free_token "token_t *tok"
|
|
.Sh DESCRIPTION
|
|
The BSM API generally manages deallocation of
|
|
.Vt token_t
|
|
objects.
|
|
However, if
|
|
.Xr au_write 3
|
|
is passed a bad audit descriptor, the
|
|
.Vt "token_t *"
|
|
parameter will be left untouched.
|
|
In that case, the caller can deallocate the
|
|
.Vt token_t
|
|
using
|
|
.Fn au_free_token
|
|
if desired.
|
|
.Pp
|
|
The
|
|
.Fa tok
|
|
argument is a
|
|
.Vt "token_t *"
|
|
generated by one of the
|
|
.Fn au_to_*
|
|
BSM API calls.
|
|
For convenience,
|
|
.Fa tok
|
|
may be
|
|
.Dv NULL ,
|
|
in which case
|
|
.Fn au_free_token
|
|
returns immediately.
|
|
.Sh IMPLEMENTATION NOTES
|
|
This is, in fact, what
|
|
.Xr audit_write 3
|
|
does, in keeping with the existing memory management model of the BSM API.

The OpenBSM implementation was created by McAfee Research, the security

division of McAfee Inc., under contract to Apple Computer, Inc., in 2004.
|
|
It was subsequently adopted by the TrustedBSD Project as the foundation for
|
|
the OpenBSM distribution.
