getwidth(3C) Standard C Library Functions getwidth(3C)NAMEgetwidth - get codeset information
SYNOPSIS
#include <euc.h>
#include <getwidth.h>
void getwidth(eucwidth_t *ptr);
DESCRIPTION
The getwidth() function reads the character class table for the current
locale to get information on the supplementary codesets. getwidth()
sets this information into the struct eucwidth_t. This struct is
defined in <euc.h> and has the following members:
short int _eucw1,_eucw2,_eucw3;
short int _scrw1,_scrw2,_scrw3;
short int _pcw;
char _multibyte;
Codeset width values for supplementary codesets 1, 2, and 3 are set in
_eucw1, _eucw2, and _eucw3, respectively. Screen width values for sup‐
plementary codesets 1, 2, and 3 are set in _scrw1, _scrw2, and _scrw3,
respectively.
The width of Extended Unix Code (EUC) Process Code is set in _pcw. The
_multibyte entry is set to 1 if multibyte characters are used, and set
to 0 if only single-byte characters are used.

The getwidth() function can be used safely in a multithreaded applica‐
tion, as long as setlocale(3C) is not being called to change the
locale.
The getwidth() function will only work with EUC locales.
