WCSWIDTH(3)                Linux Programmer's Manual               WCSWIDTH(3)

NAME
       wcswidth  -  determine  columns  needed for a fixed-size wide-character
       string

SYNOPSIS
       #define _XOPEN_SOURCE
       #include <wchar.h>

       int wcswidth(const wchar_t *s, size_t n);

DESCRIPTION
       The wcswidth() function returns the number of columns needed to  repre-
       sent  the  wide-character  string  pointed  to by s, but at most n wide
       characters.  If a nonprintable wide character occurs among these  char-
       acters, -1 is returned.

RETURN VALUE
       The  wcswidth() function returns the number of column positions for the
       wide-character string s, truncated to at most length n.

CONFORMING TO
       POSIX.1-2001.

NOTES
       The behavior of wcswidth() depends on the LC_CTYPE category of the cur-
       rent locale.
