Standard C Library Functions                         getwidth(3C)



NAME
     getwidth - get codeset information

SYNOPSIS
     #include 
     #include 

     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  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 char-
     acters are used, and set to 0 if only single-byte characters
     are used.

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


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