32.Sh NAME
33.Nm au_bsm_to_fcntl_cmd ,
34.Nm au_fcntl_cmd_to_bsm
35.Nd "convert between BSM and local fcntl(2) command values"
36.Sh LIBRARY
37.Lb libbsm
38.Sh SYNOPSIS
39.In bsm/libbsm.h
40.Ft int
41.Fn au_bsm_to_fcntl_cmd "u_short bsm_fcntl_cmd" "int *local_fcntl_cmdp"
42.Ft u_short
43.Fn au_fcntl_cmd_to_bsm "int local_fcntl_cmd"
44.Sh DESCRIPTION
45These interfaces may be used to convert between the local and BSM
46.Xr fcntl 2
47command values.
48The
49.Fn au_bsm_to_fcntl_cmd
50function accepts a BSM command value,
51.Fa bsm_fcntl_cmd ,
52and converts it to a local command value passed to
53.Xr fcntl 2 ,
54that will be stored in the integer pointed to by
55.Fa local_fcntl_cmdp
56if successful.
57This call will fail if the BSM command value cannot be mapped into a local
58.Xr fcntl 2
59command value which may occur if the command token was generated on another
60operating system.
61.Pp
62The
63.Fn au_fcntl_cmd_to_bsm
64function accepts a local
65.Xr fcntl 2
66command value, and returns the BSM
67.Xr fcntl 2
68command value for it.  This call cannot fail, and instead returns a BSM
69command value indicating to a later decoder that the command value could
70not be encoded.
71.Sh RETURN VALUES
72On success,
73.Fn au_bsm_to_fcntl_cmd
74returns 0 and a converted command value; on failure, it returns -1 but does
75not set
76.Xr errno 2 .
