29 This describes some private interfaces currently provided by praudit.
30 In the future these may be provided by libbsm instead. Note that
31 these interfaces are MT-Safe.
35 print_audit, print_audit_buf - format and print audit trail data
36 print_audit_xml_prolog,
37 print_audit_xml_ending,
38 print_audit_xml_prolog_buf,
39 print_audit_xml_ending_buf - print audit XML prolog and ending
42 int print_audit(const int flags, const char *separator);
44 int print_audit_buf(char **in_buf, int *in_buf_len, char **out_buf,
45 int *out_buf_len, const int flags, const char *separator);
47 void print_audit_xml_prolog(void);
48 void print_audit_xml_ending(void);
49 int print_audit_xml_prolog_buf(char *out_buf, const int out_buf_len);
50 int print_audit_xml_ending_buf(char *out_buf, const int out_buf_len);
53 print_audit() formats binary audit data from stdin and prints in
54 ASCII on stdout. print_audit_buf() formats binary audit data from
55 in_buf and copies in ASCII to out_buf, terminating with a null
58 print_audit_xml_prolog and print_audit_xml_prolog_buf will print
59 only the audit XML prolog. The XML, prolog includes identification
60 of the DTD which is used to parse the XML, and also identifies the
61 stylesheet which is used to view the XML conveniently (for example
62 in a browser which supports these features).
64 print_audit_xml_ending and print_audit_xml_ending_buf print only
65 the XML ending which completes the audit XML.
68 flags - specifies the types of formatting to be done:
71 Default formatting. By default, times, user and group IDs
72 (UIDs and GIDs, respectively) are converted to their ASCII
73 representation. Record type and event fields are converted
74 to their ASCII representation. If any other flags are
75 specified they will override this flag.
78 Print records in their raw form. Times, UIDs, GIDs,
79 record types, and events are displayed as integers.
80 This value and PRF_SHORTM are exclusive. If both
81 are used, no processing is done and EINVAL is returned.
84 Print records in their short form. All numeric fields
85 are converted to ASCII and displayed. The short ASCII
86 representations for the record type and event fields
87 are used. This value an PRF_RAWM are exclusive. If
88 both are used, no processing is done and EINVAL is returned.
91 Print records in XML format. "tags" are included in the
92 output to identify tokens and fields within tokens.
93 Output will not include an XML prolog or ending which
94 are required to from complete, valid XML. The various
95 print XML prolog and ending functions described here
96 must be used separately from print_audit and print_audit_buf
100 Prints one line per record. The record type and event
101 fields are always converted to their short ASCII
102 representation as is done for the -s option.
106 if non-NULL, this is used as the field delimiter instead of the
107 default delimiter, which is the comma. The maximum size of a
108 delimiter is three characters (not counting the required
109 null-terminator). Note that the delimiter is not meaningful
110 and this parameter is ignored when flags specifies XML format.
113 out_buf, out_buf_len -
114 pointers to the start of input and output buffers and their lengths.
115 See Return Values for details about how these are used.
119 print_audit() and print_audit_buf() return:
121 -1 on failure and set errno to indicate the error:
123 EINVAL - invalid input flags, delimiter, or error parsing the
126 ENOSPC - output buffer too small.
128 EIO - input exhausted before end of an audit record.
130 EPERM - internal or other unexpected error.
132 Partial results may also be returned for these errors.
135 The following parameters are always returned:
139 updated to reflect size of output successfully produced. If
140 non-zero, this will include the single terminating null byte.
143 Upon return of partial results, these parameters will also be
144 updated to reflect status (up to the end of the last completed
145 audit record from the input):
149 updated to reflect amount of input successfully consumed. in_buf
150 will point to the next byte which has not been processed.
151 in_buf_len will be set to the remaining size from this address to
152 the end of the original buffer.
155 print_audit_xml_prolog_buf and print_audit_xml_ending_buf return:
157 -1 on failure and set errno to indicate the error:
159 ENOSPC - output buffer too small.
163 The following code fragment takes audit input from stdin, and
164 will print on stdout complete XML including a prolog:
166 print_audit_xml_prolog();
169 * Format audit data from stdin and print to stdout.
171 retstat = print_audit(PRF_XMLM | PRF_ONELINE, NULL);
174 print_audit_xml_ending();
