WCWIDTH(3)                 Linux Programmer's Manual                WCWIDTH(3)

       wcwidth - determine columns needed for a wide character

       #define _XOPEN_SOURCE       /* See feature_test_macros(7) */
       #include <wchar.h>

       int wcwidth(wchar_t c);

       The  wcwidth()  function returns the number of columns needed to repre-
       sent the wide character c.  If c is a  printable  wide  character,  the
       value is at least 0.  If c is null wide character (L'\0'), the value is
       0.  Otherwise, -1 is returned.

       The wcwidth() function returns the number of column positions for c.

   Multithreading (see pthreads(7))
       The wcwidth() function is  thread-safe  with  exceptions.   It  can  be
       safely  used  in multithreaded applications, as long as setlocale(3) is
       not called to change the locale during its execution.


       Note that glibc before 2.2.5 used the prototype
       int wcwidth(wint_t c);

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