30.Sh NAME
31.Nm sysdecode_abi_to_freebsd_errno ,
32.Nm sysdecode_freebsd_to_abi_errno
33.Nd translate error numbers between process ABIs
34.Sh LIBRARY
35.Lb libsysdecode
36.Sh SYNOPSIS
37.In sysdecode.h
38.Ft int
39.Fn sysdecode_abi_to_freebsd_errno "enum sysdecode_abi abi" "int error"
40.Ft int
41.Fn sysdecode_freebsd_to_abi_errno "enum sysdecode_abi abi" "int error"
42.Sh DESCRIPTION
43The
44.Fn sysdecode_abi_to_freebsd_errno
45function returns the native
46.Xr errno 2
47value that corresponds to the error indicated by
48.Fa error
49for the process ABI
50.Fa abi .
51If
52.Fa error
53does not identify a valid error for
54.Fa abi ,
55.Dv INT_MAX
56is returned.
57.Pp
58The
59.Fn sysdecode_freebsd_to_abi_errno
60function the error value for the process ABI
61.Fa abi
62that corresponds to the native
63.Xr errno 2
64value
65.Fa error .
66If
67.Fa error
68does not identify a valid
69.Xr errno 2
70error,
71.Dv INT_MAX
72is returned.
73.Pp
74Note that the mappings between native
75.Xr errno 2
76values and errors for other ABIs are not exhaustive.
77If a mapping does not exist,
78these functions return
79.Dv INT_MAX .
80In addition, multiple error values in one ABI may map to a single
81error in another ABI.
82.Sh RETURN VALUES
83These functions return an error value on success or
84.Dv INT_MAX
85if
86.Fa error
87is not valid.
88.Pp
