NAME

       cset, csetlen, csetcol, csetno, wcsetno - get information on EUC codesets

SYNOPSIS

       #include <euc.h>

       int csetlen(int codeset);

       int csetcol(int codeset);

       int csetno(unsigned char c);

       #include <widec.h>

       int wcsetno(wchar_t pc);

DESCRIPTION

       Both  csetlen()	and  csetcol()	take a code set number	codeset, which must be 0, 1, 2, or 3. The csetlen() function returns the number of
       bytes needed to represent a character of the given Extended Unix Code (EUC) code set, excluding the single-shift characters SS2 and SS3 for
       codesets 2 and 3. The csetcol() function returns the number of columns a character in the given EUC code set would take on the display.

       The  csetno() function is implemented as a macro that returns a codeset number (0, 1, 2, or 3) for the EUC character whose first byte is c.
       For example,

	 #include<euc.h>
	 ...
	 x+=csetcol(csetno(c));

       increments a counter "x" (such as the cursor position) by the width of the character whose first byte is c.

       The wcsetno() function is implemented as a macro that returns a codeset number (0, 1, 2, or 3) for the given process code character pc. For
       example,

	 #include<euc.h>
	 #include<widec.h>
	 ...
	 x+=csetcol(wcsetno(pc));

       increments a counter "x" (such as the cursor position) by the width of the Process Code character pc.

USAGE

       These functions work only for the EUC locales.

       The  cset(),  csetlen(),  csetcol(),  csetno(), and wcsetno() functions can be used safely in multithreaded applications, as long as setlo-
       cale(3C) is not being called to change the locale.
