.SH DESCRIPTION
|
||
|
|
.BR _mapErr
|
||
|
|
takes a GS/OS error code
|
||
|
|
.IR err
|
||
|
|
(typically returned by
|
||
|
|
.BR toolerror (3)
|
||
|
|
or taken from the value of the global integer
|
||
|
|
.BR _toolErr )
|
||
|
|
and maps it to a UNIX error code suitable for use with
|
||
|
|
.BR perror (3)
|
||
|
|
and related routines.
|
||
|
|
.LP
|
||
|
|
If
|
||
|
|
.IR err
|
||
|
|
is zero,
|
||
|
|
.BR _mapErr
|
||
|
|
returns zero.
|
||
|
|
If there is no direct mapping, then
|
||
|
|
.BR EIO
|
||
|
|
is returned.
