28.Sh NAME
29.Nm sysdecode_abi_to_freebsd_errno ,
30.Nm sysdecode_freebsd_to_abi_errno
31.Nd translate error numbers between process ABIs
32.Sh LIBRARY
33.Lb libsysdecode
34.Sh SYNOPSIS
35.In sysdecode.h
36.Ft int
37.Fn sysdecode_abi_to_freebsd_errno "enum sysdecode_abi abi" "int error"
38.Ft int
39.Fn sysdecode_freebsd_to_abi_errno "enum sysdecode_abi abi" "int error"
40.Sh DESCRIPTION
41The
42.Fn sysdecode_abi_to_freebsd_errno
43function returns the native
44.Xr errno 2
45value that corresponds to the error indicated by
46.Fa error
47for the process ABI
48.Fa abi .
49If
50.Fa error
51does not identify a valid error for
52.Fa abi ,
53.Dv INT_MAX
54is returned.
55.Pp
56The
57.Fn sysdecode_freebsd_to_abi_errno
58function the error value for the process ABI
59.Fa abi
60that corresponds to the native
61.Xr errno 2
62value
63.Fa error .
64If
65.Fa error
66does not identify a valid
67.Xr errno 2
68error,
69.Dv INT_MAX
70is returned.
71.Pp
72Note that the mappings between native
73.Xr errno 2
74values and errors for other ABIs are not exhaustive.
75If a mapping does not exist,
76these functions return
77.Dv INT_MAX .
78In addition, multiple error values in one ABI may map to a single
79error in another ABI.
80.Sh RETURN VALUES
81These functions return an error value on success or
82.Dv INT_MAX
83if
84.Fa error
85is not valid.
86.Pp
