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

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.

Notes

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