.Sh SYNOPSIS
|
|
.In sysdecode.h
|
|
.Ft int
|

|
|

|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn sysdecode_abi_to_freebsd_errno
|
|
function returns the native
|
|
.Xr errno 2
|
|
value that corresponds to the error indicated by
|
|
.Fa error
|
|
for the process ABI
|
|
.Fa abi .
|
|
If
|
|
.Fa error
|
|
does not identify a valid error for
|
|
.Fa abi ,
|
|
.Dv INT_MAX
|
|
is returned.
|
|
.Pp
|
|
The
|
|
.Fn sysdecode_freebsd_to_abi_errno
|
|
function the error value for the process ABI
|
|
.Fa abi
|
|
that corresponds to the native
|
|
.Xr errno 2
|
|
value
|
|
.Fa error .
|
|
If
|
|
.Fa error
|
|
does not identify a valid
|
|
.Xr errno 2
|
|
error,
|
|
.Dv INT_MAX
|
|
is returned.
|
|
.Pp
|
|
Note that the mappings between native
|
|
.Xr errno 2
|
|
values and errors for other ABIs are not exhaustive.
|
|
If a mapping does not exist,
|
|
these functions return
|
|
.Dv INT_MAX .
|
|
In addition, multiple error values in one ABI may map to a single
|
|
error in another ABI.
|
|
.Sh RETURN VALUES
|
|
These functions return an error value on success or
|
|
.Dv INT_MAX
|
|
if
|
|
.Fa error
|
|
is not valid.
|
|
.Pp
