Имя (Name)
iswxdigit - test for hexadecimal digit wide character
Синопсис (Synopsis)
#include <wctype.h>
int iswxdigit(wint_t wc);
Описание (Description)
The iswxdigit() function is the wide-character equivalent of the
isxdigit(3) function. It tests whether wc is a wide character
belonging to the wide-character class "xdigit".
The wide-character class "xdigit" is a subclass of the wide-
character class "alnum", and therefore also a subclass 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 "xdigit" is disjoint from the wide-character
class "cntrl".
Being a subclass of the wide-character class "graph", the wide-
character class "xdigit" 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 "xdigit" is disjoint from the wide-character
class "punct".
The wide-character class "xdigit" always contains at least the
letters 'A' to 'F', 'a' to 'f' and the digits '0' to '9'.
Возвращаемое значение (Return value)
The iswxdigit() function returns nonzero if wc is a wide
character belonging to the wide-character class "xdigit".
Otherwise, it returns zero.
