AU_BSM_TO_ERRNO(3)       BSD Library Functions Manual       AU_BSM_TO_ERRNO(3)

NAME
     au_bsm_to_errno, au_errno_to_bsm, au_strerror -- convert between BSM and local error numbers

LIBRARY
     Basic Security Module Library (libbsm, -lbsm)

SYNOPSIS
     #include <bsm/libbsm.h>

     int
     au_bsm_to_errno(u_char bsm_error, int *errorp);

     u_char
     au_errno_to_bsm(int error);

     const char *
     au_strerror(int bsm_error);

DESCRIPTION
     These interfaces may be used to convert between the local ( errno(2)) and BSM error number spaces found
     in BSM return tokens.

     The au_bsm_to_errno() function accepts a BSM error value, bsm_error, and converts it to an errno(2)
     that will be stored in the integer pointed to by errorp if successful.  This call will fail if the BSM
     error cannot be mapped into a local error number, which may occur if the return token was generated on
     another operating system.

     The au_errno_to_bsm() function accepts a local errno(2) value, and returns the BSM error number for it.
     This call cannot fail, and instead returns a BSM error number indicating to a later decoder that the
     error could not be encoded.

     The au_strerror() function converts a BSM error value to a string, generally by converting first to a
     local error number and using the local strerror(3) function, but will also work for errors that are not
     locally defined.

RETURN VALULES
     On success, au_bsm_to_errno() returns 0 and a converted error value; on failure, it returns -1 but does
     not set errno(2).

     On success, au_strerror() returns a pointer to an error string; on failure it will return NULL.

HISTORY
     au_bsm_to_errno() and au_errno_to_bsm() were introduced in OpenBSM 1.1.

AUTHORS
     These functions were implemented by Robert Watson under contract to Apple Inc.

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

BUGS
     au_strerror is unable to provide localized strings for errors not available in the local operating sys-tem. system.
