euclen(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.
