NAME
wcswidth - number of column positions of a wide-character string SYNOPSIS
#include <wchar.h> int wcswidth(const wchar_t *pwcs, size_t n); DESCRIPTION
The wcswidth() function determines the number of column positions required for n wide-character codes (or fewer than n wide-character codes if a null wide-character code is encountered before n wide-character codes are exhausted) in the string pointed to by pwcs. RETURN VALUES
The wcswidth() function either returns 0 (if pwcs points to a null wide-character code), or returns the number of column positions to be occupied by the wide-character string pointed to by pwcs, or returns -1 (if any of the first n wide-character codes in the wide-character string pointed to by pwcs is not a printing wide-character code). ERRORS
No errors are defined. ATTRIBUTES

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''). BSD
