_MAPERR(3)                     Library Routines                     _MAPERR(3)

NAME

       _mapErr - map GS/OS error codes to UNIX errno codes

SYNOPSIS

       #include <gno/gno.h>

       int _mapErr(int err);

DESCRIPTION

       _mapErr  takes  a  GS/OS  error code err (typically returned by tooler����
       ror(3) or taken from the value of the global integer _toolErr) and maps
       it  to  a  UNIX  error code suitable for use with perror(3) and related
       routines.

       If err is zero, _mapErr returns zero.  If there is no  direct  mapping,
       then EIO is returned.
