NAME    [Toc]    [Back]

     getwidth -	get information	on supplementary code sets

SYNOPSIS    [Toc]    [Back]

     #include <sys/euc.h>
     #include <getwidth.h>

     void getwidth(eucwidth_t *ptr<b>);

DESCRIPTION    [Toc]    [Back]

     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.
