au_read_rec

 - perform I/O involving an audit record

LIBRARY

Lb libbsm

SYNOPSIS

#include <bsm/libbsm.h>
int au_fetch_tok (tokenstr_t *tok u_char *buf int len);
void Fo au_print_tok Fa FILE *outfp tokenstr_t *tok char *del char raw char sfrm Fc Ft int au_read_rec (FILE *fp u_char **buf);

DESCRIPTION

These interfaces support input and output (I/O) involving audit records, internalizing an audit record from a byte stream, converting a token to either a raw or default string, and reading a single record from a file.

The au_fetch_tok ();
function reads a token from the passed buffer Fa buf of length Fa len bytes, and returns a pointer to the token via Fa tok .

The au_print_tok ();
function prints a string form of the token Fa tok to the file output stream Fa outfp , either in default mode, or raw mode if Fa raw is set non-zero. The delimiter Fa del is used when printing.

The au_read_rec ();
function reads an audit record from the file stream Fa fp , and returns an allocated memory buffer containing the record via Fa *buf , which must be freed by the caller using free(3).

A typical use of these routines might open a file with fopen(3), then read records from the file sequentially by calling au_read_rec (.);
Each record would be broken down into components tokens through sequential calls to au_fetch_tok ();
on the buffer, and then invoking au_print_tok ();
to print each token to an output stream such as stdout On completion of the processing of each record, a call to free(3) would be used to free the record buffer. Finally, the source stream would be closed by a call to fclose(3).

RETURN VALUES

The au_fetch_tok ();
and au_read_rec ();
functions return 0 on success, or -1 on failure along with additional error information returned via errno

HISTORY

The OpenBSM implementation was created by McAfee Research, the security division of McAfee Inc., under contract to Apple Computer, Inc., in 2004. It was subsequently adopted by the TrustedBSD Project as the foundation for the OpenBSM distribution.
