EUCLEN(3C) Standard C Library Functions 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, including 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 determine 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 applications, as
long as
setlocale(3C) is not called to change the locale.
