ERRORS

Fa fileid
is filled into the structure pointed to by
Fa stat
unless:
Bq Er ENOENT
The file was not found (probably not loaded).
Bq Er EINVAL
The version specified in the
Fa version

You would need to rebuild world, the
kernel, or your application, if this error occurs, given that you did properly
fill in the
Fa version
field.
Bq Er EFAULT
There was a problem copying one, some, or all of the fields into
Fa stat
in the
