45 function provides a generic programming interface for audit record submission.
46 This audit record will contain a header, subject token, an optional text token,
47 return token, and a trailer.
48 The header will contain the event class specified by
50 The subject token will be generated based on
52 The return token is dependent on the
56 arguments; unlike the argument to
59 should be a local rather than BSM error number.
60 Optionally, a text token will be created as a part of this record.
62 Text token output is under the control of a
64 string that specifies how subsequent arguments (or arguments accessed via the
65 variable-length argument facilities of
67 are converted for output.
72 then no text token is created in the audit record.
74 It should be noted that
80 has already been called.
81 As a direct result, the terminal ID for the
82 subject will be retrieved from the kernel via
90 Otherwise a -1 is returned and the global variable
92 is set to indicate the error.
