AU_IO(3)               FreeBSD Library Functions Manual               AU_IO(3)

NAME
     au_fetch_tok, au_print_tok, au_read_rec -- Perform I/O involving an audit
     record

LIBRARY
     Basic Security Module User Library (libbsm, -lbsm)

SYNOPSIS
     #include <libbsm.h>

     int
     au_fetch_tok(tokenstr_t *tok, u_char *buf, int len);

     void
     au_print_tok(FILE outfp, tokenstr_t *tok, char *del, char raw,
         char sfrm);

     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.

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

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

     au_read_rec() reads an audit record from the file stream fp, and returns
     an allocated memory buffer containing the record via *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
     au_fetch_tok() and au_read_rec() return 0 on success, or -1 on failure
     along with additional error information returned via errno.

SEE ALSO
     free(3), libbsm(3)

AUTHORS
     This software was created by Robert Watson, Wayne Salamon, and Suresh
     Krishnaswamy for McAfee Research, the security research division of
     McAfee, Inc., under contract to Apple Computer, Inc.

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

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.

BUGS
     errno may not always be properly set in the event of an error.
