DESCRIPTION

The setac() function resets the database iterator to the beginning of the database; see the BUGS section for more information.

The endac() function closes the audit_control(5) database.

The getacdir() function returns the name of the directory where log data is stored via the passed character buffer name of length len.

The getacdist() function returns a value that allows to decide if trail files distribution is turned on or off.

The getacexpire() function returns the audit trail file expiration parameters in the passed int buffer andflg, time_t buffer age and size_t buffer size. If the parameter is not specified in the audit_control(5) file it is set to zero.

The getacfilesz() function returns the audit trail rotation size in the passed size_t buffer size_val.

The getacflg() function returns the audit system flags via the the passed character buffer auditstr of length len.

The getachost() function returns the local systems's audit host information via the the passed character buffer auditstr of length len.

The getacmin() function returns the minimum free disk space for the audit log target file system via the passed min_val variable.

The getacna() function returns the non-attributable flags via the passed character buffer auditstr of length len.

The getacpol() function returns the audit policy flags via the passed character buffer auditstr of length len.

The getacqsize() function returns the size of the audit post-commit queue in the passed size_val buffer. If the parameter is not specified in the audit_control(5) file it is set to -1, indicating that the kernel's default queue size is being used.

The au_poltostr() function converts a numeric audit policy mask, policy, to a string in the passed character buffer buf of lenth maxsize.

The au_strtopol() function converts an audit policy flags string, polstr, to a numeric audit policy mask returned via policy.

RETURN VALUES

The au_poltostr() function returns a string length of 0 or more on success, or a negative value on if there is a failure.

The getacdist() function returns 1 if trail files distribution is turned on, 0 if it is turned off or negative value on failure.

Functions that return a string value will return a failure if there is insufficient room in the passed character buffer for the full string.

AUTHORS

The Basic Security Module (BSM) interface to audit records and audit event stream format were defined by Sun Microsystems.

BUGS

There is no reason for the setac() interface to be exposed as part of the public API, as it is called implicitly by other access functions and iteration is not supported.

These interfaces inconsistently return various negative values depending on the failure mode, and do not always set errno on failure.
