euccol(3C)

NAME

     euclen, euccol, eucscol - get byte length and display  width
     of EUC characters

SYNOPSIS

     #include <euc.h>

     int euclen(const unsigned char *s);

     int euccol(const unsigned char *s);

     int eucscol(const unsigned char *str);

DESCRIPTION

     The euclen() function returns the length  in  bytes  of  the
     Extended  Unix Code (EUC) character pointed to by s, includ-
     ing single-shift characters, if present.

     The euccol() function returns the screen column width of the
     EUC character pointed to by s.

     The eucscol() function returns the screen  column  width  of
     the EUC string pointed to by str.

     For the euclen() and euccol(), functions, s  points  to  the
     first byte of the character. This byte is examined to deter-
     mine its codeset.  The character type table for the  current
     locale  is  used  for  codeset byte length and display width
     information.

USAGE

     These functions will work only with EUC locales.

     These functions can be used safely in multithreaded applica-
     tions,  as long as setlocale(3C) is not called to change the
     locale.
