eucset(1)                      DG/UX R4.11MU05                     eucset(1)


NAME
       eucset - set or get EUC code set widths

SYNOPSIS
       eucset [ cswidth ]
       eucset -p

DESCRIPTION
       eucset assumes the existence of an line discipline which does
       canonical processing of EUC character in its standard input STREAM
       (usually a TTY).  The line discipline must recognize the eucioc calls
       to ioctl(), as defined in the header file
       /usr/include/sys/eucioctl.h.

       If given no arguments, eucset looks in the environment for the
       cswidth parameter in the character class table, which is assumed to
       specify the code Set widths and Screen widths in use.  The format of
       cswidth parameter is described in character class table
       specification.

       If given one argument which does not begin with "-", it is taken to
       be a string in the format of cswidth parameter, overriding whatever
       is in the environment.

       If given the optional argument -p, eucset prints the current values
       of the code set widths and screen widths as returned by the line
       discipline.  These values may be different than what is currently in
       the user's environment, but represent the EUC mapping that the EUC
       line discipline is currently using.  The primary code set (ASCII) is
       excluded from the listing, which is in the same format as cswidth
       parameter.

RETURN VALUES
       eucset returns 0 on success, 1 for failure of any call to ioctl().
