NAME
     wcwidth - number of column  positions  of  a  wide-character
     code

SYNOPSIS
     #include 

     int wcwidth(wchar_t wc);


DESCRIPTION
     The wcwidth() function determines the number of column posi-
     tions  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 posi-
     tions 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.
