au_free_token(3)

au_free_token3

Deallocate a token_t created by any of the au_to_*() bsm api functions

Usage

#include <bsm/libbsm.h>

void

au_free_token(token_t *tok);

Library

library “libbsm”

Overview

The BSM API generally manages deallocation of token_t objects. However, if au_write(3) is passed a bad audit descriptor, the token_t * parameter will be left untouched. In that case, the caller can deallocate the token_t using au_free_token() if desired.

The tok argument is a token_t * generated by one of the au_to_*() BSM API calls. For convenience, tok may be NULL, in which case au_free_token() returns immediately.

Implementation notes

This is, in fact, what audit_write(3) does, in keeping with the existing memory management model of the BSM API.
