SYNOPSIS

DESCRIPTION

16       The getwidth() function reads the character class table for the current
17       locale to get information on  the  supplementary  codesets.  getwidth()
18       sets  this  information  into  the  struct  eucwidth_t.  This struct is
19       defined in <euc.h> and has the following members:
20
21         short int   _eucw1,_eucw2,_eucw3;
22         short int   _scrw1,_scrw2,_scrw3;
23         short int   _pcw;
24         char        _multibyte;
25
26
27
28       Codeset width values for supplementary codesets 1, 2, and 3 are set  in
29       _eucw1,  _eucw2, and _eucw3, respectively. Screen width values for sup‐
30       plementary codesets 1, 2, and 3 are set in _scrw1, _scrw2, and  _scrw3,
31       respectively.
32
33
34       The width of  Extended Unix Code (EUC) Process Code is set in _pcw. The
35       _multibyte entry is set to 1 if multibyte characters are used, and  set
36       to 0 if only single-byte characters are used.

NOTES

53       The  getwidth() function can be used safely in a multithreaded applica‐
54       tion, as long as setlocale(3C)  is  not  being  called  to  change  the
55       locale.
56
57
58       The getwidth() function will only work with EUC locales.
