NAME

       iswgraph - test for a visible wide-character code

SYNOPSIS

       #include <wctype.h>

       int iswgraph(wint_t wc);

DESCRIPTION

       The  iswgraph() function shall test whether wc is a wide-character code representing a character of class
       graph in the program's current locale; see the Base Definitions volume of  IEEE Std 1003.1-2001,  Chapter
       7, Locale.

       The  wc  argument  is  a wint_t, the value of which the application shall ensure is a wide-character code
       corresponding to a valid character in the current locale, or equal to the value of the macro WEOF. If the
       argument has any other value, the behavior is undefined.

RETURN VALUE

       The  iswgraph()  function  shall  return  non-zero  if  wc  is  a  wide-character  code  with  a  visible
       representation; otherwise, it shall return 0.

ERRORS

       No errors are defined.

APPLICATION USAGE

       To ensure applications portability, especially across natural languages, only  this  function  and  those
       listed in the SEE ALSO section should be used for classification of wide-character codes.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
