DESCRIPTION

au_open() allocates an audit record descriptor to which audit tokens can be written using au_write().

au_close() terminates the life of an audit record d of type event started by au_open(). If the keep parameter is zero, the data contained therein is discarded and the memory used is given up by calling free(3C). Otherwise, the additional parameters are used to create a header token. Depending on the audit policy information obtained by auditon(2), additional tokens such as sequence and trailer tokens may be added to the record. au_close() finally writes the record to the audit trail by calling audit(2).

au_write() adds the audit token pointed to by m to the audit record identified by the descriptor d. After this call is made the audit token is no longer available to the caller.

RETURN VALUES

A successful invocation for all calls will return a 0.

au_open() returns −1 if a descriptor could not be allocated. au_close() and au_write() return −1 if d is not a valid descriptor or if audit(2) experienced an error. In the latter case, errno is set to indicate the error.
