eucset(1)                      06 Dec 1994                        eucset(1)

NAME
     eucset - set or get EUC code set widths

SYNOPSIS
     eucset [ -p ]

DESCRIPTION
     eucset assumes the existence of a line discipline which does canonical
     processing of EUC characters 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 current
     locale's LC_CTYPE category, and retrieves the corresponding character
     class table, which specifies the code set widths and screen widths in
     use (see wchrtbl(1M)). It then passes this character width information
     to the line discipline.

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

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