FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

au_fetch_tok, au_print_tok, au_read_rec - perform I/O involving an audit

 

NAME

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

LIBRARY

      library “libbsm”
 

SYNOPSIS

      #include <bsm/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.
 
      The au_fetch_tok() function reads a token from the passed buffer buf of
      length len bytes, and returns a pointer to the token via tok.
 
      The au_print_tok() function 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.
 
      The au_read_rec() function 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).
      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.
 

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.
 

BUGS

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

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
