NAME

getwidth - 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 supplementary 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.  

ATTRIBUTES

NOTES

The getwidth() function can be used safely in a multithreaded application, as long as setlocale(3C) is not being called to change the locale.

The getwidth() function will only work with EUC locales.
