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.
