33.Dt AU_FREE_TOKEN 3
34.Os
35.Sh NAME
36.Nm au_free_token
37.Nd "deallocate a token_t created by any of the au_to_*() BSM API functions"
38.Sh LIBRARY
39.Lb libbsm
40.Sh SYNOPSIS
41.In bsm/libbsm.h
42.Ft void
43.Fn au_free_token "token_t *tok"
44.Sh DESCRIPTION
45The BSM API generally manages deallocation of
46.Vt token_t
47objects.
48However, if
49.Xr au_write 3
50is passed a bad audit descriptor, the
51.Vt "token_t *"
52parameter will be left untouched.
53In that case, the caller can deallocate the
54.Vt token_t
55using
56.Fn au_free_token
57if desired.
58.Pp
59The
60.Fa tok
61argument is a
62.Vt "token_t *"
63generated by one of the
64.Fn au_to_*
65BSM API calls.
66For convenience,
67.Fa tok
68may be
69.Dv NULL ,
70in which case
71.Fn au_free_token
72returns immediately.
73.Sh IMPLEMENTATION NOTES
74This is, in fact, what
75.Xr audit_write 3
76does, in keeping with the existing memory management model of the BSM API.
77.Sh SEE ALSO
78.Xr audit_write 3 ,
79.Xr au_write 3 ,
80.Xr libbsm 3
81.Sh HISTORY
82The OpenBSM implementation was created by McAfee Research, the security
83division of McAfee Inc., under contract to Apple Computer, Inc., in 2004.
84It was subsequently adopted by the TrustedBSD Project as the foundation for
85the OpenBSM distribution.
