NAME
       getwidth - get information of supplementary code sets

SYNOPSIS
       #include <sys/euc.h>
       #include <getwidth.h>
       void getwidth(eucwidth_t *ptr);

DESCRIPTION
       getwidth() reads the character class table, which is generated by
       chrtbl or wchrtbl, to get information of supplementary code sets, and
       sets it into the structure eucwidth_t.

       The structure eucwidth_t is defined in the header file
       /usr/include/sys/euc.h as follows:

           typedef struct {
               short int _eucw1,_eucw2,_eucw3;
               short int _scrw1,_scrw2,_scrw3;
               short int _pcw;
               char_multibyte;
           } eucwidth_t;


       Code set width values for three supplementary code sets are set in
       _eucw1, _eucw2 and _eucw3, respectively.  Screen width values for the
       three supplementary code sets are set in _scrw1, _scrw2 and _scrw3,
       respectively.  The width of EUC process code is set in _pcw.  The
       maximum width in bytes of EUC is set in _multibyte.

       If the cswidth parameter is not set, the system default is required.
       The system default is cswidth 1:1,0:0,0:0.
