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.

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. SunOS 5.11 20 Dec 1996 getwidth(3C)
