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.
