AU_BSM_TO_SOCKET_TYPE(3)                      FreeBSD Library Functions Manual

NAME
     au_bsm_to_socket_type, au_socket_type_to_bsm - convert between BSM and
     local socket types

LIBRARY
     Basic Security Module Library (libbsm, -lbsm)

SYNOPSIS
     #include <bsm/libbsm.h>

     int
     au_bsm_to_socket_type(u_short bsm_socket_type, int *local_socket_typep);

     u_short
     au_socket_type_to_bsm(int local_socket_type);

DESCRIPTION
     These interfaces may be used to convert between the local and BSM socket
     types.  The au_bsm_to_socket_type() function accepts a BSM socket type,
     bsm_socket_type, and converts it to a local socket type, such as those
     passed to socket(2), that will be stored in the integer pointed to by
     local_socket_typep if successful.  This call will fail if the BSM socket
     type cannot be mapped into a local socket type, which may occur if the
     socket token was generated on another operating system.

     au_socket_type_to_bsm() function accepts a local socket type, and returns
     the BSM socket type for it.  This call cannot fail, and instead returns a
     BSM socket type indicating to a later decoder that the socket type could
     not be encoded.

RETURN VALUES
     On success, au_bsm_to_socket_type() returns 0 and a converted socket
     type; 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_socket_type() and au_socket_type_to_bsm() were introduced in
     OpenBSM 1.1.

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