getwidth(3c) [sunos man page]

getwidth(3C)						   Standard C Library Functions 					      getwidth(3C)

NAME

       getwidth - get codeset information

SYNOPSIS

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

       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 <euc.h> 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 characters are used, and
       set to 0 if only single-byte characters are used.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |

       +-----------------------------+-----------------------------+

SEE ALSO

       euclen(3C), setlocale(3C), attributes(5)

NOTES

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

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

NAME

       euclen, euccol, eucscol - get byte length and display width of EUC characters

SYNOPSIS

       #include <euc.h>

       int euclen(const unsigned char *s);

       int euccol(const unsigned char *s);

       int eucscol(const unsigned char *str);

DESCRIPTION

       The euclen() function returns the length in bytes of the Extended Unix Code (EUC) character pointed to by s, including single-shift charac-
       ters, if present.

       The euccol() function returns the screen column width of the EUC character pointed to by s.

       The eucscol() function returns the screen column width of the EUC string pointed to by str.

       For the euclen() and euccol(), functions, s points to the first byte of the character. This byte is examined to determine its codeset.  The
       character type table for the current locale is used for codeset byte length and display width information.

USAGE

       These functions will work only with EUC locales.

       These functions can be used safely in multithreaded applications, as long as setlocale(3C) is not called to change the locale.
