214.Sh DESCRIPTION
215These interfaces support the allocation of BSM audit tokens, represented by
216.Vt token_t ,
217for various data types.
218.Pp
219.Xr au_errno_to_bsm 3
220must be used to convert local
221.Xr errno 2
222errors to BSM error numbers before they are passed to
223.Fn au_to_return ,
224.Fn au_to_return32 ,
225and
226.Fn au_to_return64 .
227.Sh RETURN VALUES
228On success, a pointer to a
229.Vt token_t
230will be returned; the allocated
231.Vt token_t
232can be freed via a call to
233.Xr au_free_token 3 .
234On failure,
235.Dv NULL
236will be returned, and an error condition returned via
237.Va errno .

241.Sh HISTORY
242The OpenBSM implementation was created by McAfee Research, the security
243division of McAfee Inc., under contract to Apple Computer, Inc., in 2004.
244It was subsequently adopted by the TrustedBSD Project as the foundation for
245the OpenBSM distribution.
