NAME
iswdigit - test for decimal digit wide character
SYNOPSIS
#include <wctype.h> int iswdigit(wint_t wc);
DESCRIPTION
The iswdigit() function is the wide-character equivalent of the isdigit(3) function. It tests whether wc is a wide character belonging to the wide-character class "digit". The wide-character class "digit" is a subclass of the wide-character class "xdigit", and therefore also a subclass of the wide-character class "alnum", of the wide-character class "graph" and of the wide- character class "print". Being a subclass of the wide character class "print", the wide- character class "digit" is disjoint from the wide-character class "cntrl". Being a subclass of the wide-character class "graph", the wide- character class "digit" is disjoint from the wide-character class "space" and its subclass "blank". Being a subclass of the wide-character class "alnum", the wide- character class "digit" is disjoint from the wide-character class "punct". The wide-character class "digit" is disjoint from the wide-character class "alpha" and therefore also disjoint from its subclasses "lower", "upper". The wide-character class "digit" always contains exactly the digits '0' to '9'.
RETURN VALUE
The iswdigit() function returns nonzero if wc is a wide character belonging to the wide-character class "digit". Otherwise, it returns zero.
