audgen - generate an audit record  


#include <sys/audit.h>
        int event,
        char *tokenp,
        char *argv[],
        char *userbuff,
        long *size);


The system call generates an audit record.

The argument event is an integer indicating the event type of the operation being audited (see The value of event must be between one of the following values: MIN_TRUSTED_EVENT and MIN_TRUSTED_EVENT + N_TRUSTED_EVENTS -1 MIN_SITE_EVENT and MIN_SITE_EVENT + n_site_events -1 The number of site-defined events, n_site_events, is determined by the sysconfig sec parameter audit_site_events. Use sysconfig -q sec to view the security configuration controlled by /etc/sysconfigtab. See aud_sitevent(3) and aud_sitevent_num(3) for information on mapping site-defined event names and event numbers.

The tokenp argument is a null-terminated array of token_type (see each of which represents the type of argument referenced by the corresponding *argv argument.

The argv argument is a pointer to an array containing either the actual arguments or pointers to those arguments that are to be recorded in the audit record. A pointer to the actual argument is placed in that array when the argument is a string, array, or other variable length structure. Arguments represented as an int or a long are placed directly in that array. The available public tokens are listed in the audit.h file.

If size is nonzero, *size is the size of userbuff provided to audgen, and the audit record created is not passed into the system audit data stream, but is copied out to userbuff. On return, *size is updated to the number of bytes of data placed into userbuff. If the size of the audit record exceeds *size, then errno is set to E2BIG. Applications can use this feature to create their own audit records.  


The call is a privileged system call. No record is generated for the system audit data stream if the specified event is not being audited for the current process. The maximum number of arguments referenced by argv is AUD_NPARAM (128) with no more than 8 of any one token_type.  


Upon successful completion, returns a value of 0. Otherwise, it returns a value of -1 and sets the global integer variable errno to indicate the error.  


The system call fails under the following conditions:

The user is not privileged for this operation.
The value supplied for the event, tokenp, or argv argument is invalid.
The audit record exceeds the audit buffer size.
Indicates an attempt to use a system call that is not configured.
The tokenmask data is invalid.
The size argument is non-zero, and the userbuff argument is invalid.
A value referenced by the argv argument is invalid.
