getwidth(3W)

NAME
     getwidth - get information on supplementary code sets

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

DESCRIPTION
     getwidth reads the character class table generated by chrtbl(1M) or
     wchrtbl(1M) to get information on supplementary code sets, and puts it in
     the structure eucwidth_t.

     The structure eucwidth_t is defined in the header file 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.
