NAME
     eucset - set or get EUC code set widths

SYNOPSIS
     eucset [ cswidth ]
     eucset -p

DESCRIPTION
     eucset assumes the existence of an EUC line discipline
     (which does canonical processing of EUC characters) in its
     standard input Stream (usually a tty). The EUC line discip-
     line must recognize the eucioc calls to ioctl(2), as defined
     in the header file sys/eucioctl.h.

     If given no arguments, eucset looks for the cswidth parame-
     ter 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 (see chrtbl(1M) and wchrtbl(1M).

     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. EUC code set 0 (ASCII) is excluded from the listing,
     which is in the same format as the cswidth parameter.

     The behavior of eucset is affected by the LC_CTYPE category
     of the current locale.

RETURN VALUES
     eucset returns 0 on success, 1 for failure of any call to
     ioctl(2).
