wcwidth(3C) Standard C Library Functions wcwidth(3C)NAME
wcwidth - number of column positions of a wide-character code
SYNOPSIS
#include <wchar.h>
int wcwidth(wchar_t wc);
DESCRIPTION
The wcwidth() function determines the number of column positions required for the wide character wc. The value of wc must be a character
representable as a wchar_t, and must be a wide-character code corresponding to a valid character in the current locale.
RETURN VALUES
The wcwidth() function either returns 0 (if wc is a null wide-character code), or returns the number of column positions to be occupied by
the wide-character code wc, or returns -1 (if wc does not correspond to a printing wide-character code).
ERRORS
No errors are defined.

WCWIDTH(3) BSD Library Functions Manual WCWIDTH(3)NAME
wcwidth, wcwidth_l -- number of column positions of a wide-character code
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <wchar.h>
int
wcwidth(wchar_t wc);
#include <wchar.h>
#include <xlocale.h>
int
wcwidth_l(wchar_t wc, locale_t loc);
DESCRIPTION
The wcwidth() function determines the number of column positions required to display the wide character wc.
Although the wcwidth() function uses the current locale, the wcwidth_l() function may be passed a locale directly. See xlocale(3) for more
information.
RETURN VALUES
The wcwidth() function returns 0 if the wc argument is a null wide character (L' '), -1 if wc is not printable; otherwise, it returns the
number of column positions the character occupies.
EXAMPLES
This code fragment reads text from standard input and breaks lines that are more than 20 column positions wide, similar to the fold(1) util-
ity:
wint_t ch;
int column, w;
column = 0;
while ((ch = getwchar()) != WEOF) {
w = wcwidth(ch);
if (w > 0 && column + w >= 20) {
putwchar(L'
');
column = 0;
}
putwchar(ch);
if (ch == L'
')
column = 0;
else if (w > 0)
column += w;
}

The wcwidth() function conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

I am attempting to replace positions 44-46 with YYY if positions 48-50 = XXX.
awk -F "" '{if (substr($0,48,3)=="XXX") $44="YYY"}1' OFS="" $filename > $tempfile
But this is not working, 44-46 is still spaces in my tempfile instead of YYY. Any suggestions would be greatly appreciated. (9 Replies)
