WCSWIDTH(3)						   BSD Library Functions Manual 					       WCSWIDTH(3)

NAME
wcswidth, wcswidth_l -- number of column positions in wide-character string
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <wchar.h> int wcswidth(const wchar_t *pwcs, size_t n); #include <wchar.h> #include <xlocale.h> int wcswidth_l(const wchar_t *pwcs, size_t n, locale_t loc);
DESCRIPTION
The wcswidth() function determines the number of column positions required for the first n characters of pwcs, or until a null wide character (L'') is encountered. Although the wcswidth() function uses the current locale, the wcswidth_l() function may be passed a locale directly. See xlocale(3) for more information.
RETURN VALUES
The wcswidth() function returns 0 if pwcs is an empty string (L""), -1 if a non-printing wide character is encountered; otherwise, it returns the number of column positions occupied.
SEE ALSO
iswprint(3), wcwidth(3), xlocale(3)
STANDARDS
The wcswidth() function conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
