SYNOPSIS

wc

DESCRIPTION

These functions test whether wc is a wide-character code representing a character of a particular class defined in the LC_CTYPE category of the current locale.

In all cases, wc is a wint_t, the value of which must be a wide-character code corresponding to a valid character in the current locale or must equal the value of the macro WEOF. If the argument has any other values, the behavior is undefined.

iswalpha(wc): Tests whether wc is a wide-character code representing a character of class "alpha" in the program's current locale.
iswupper(wc): Tests whether wc is a wide-character code representing a character of class "upper" in the program's current locale.
iswlower(wc): Tests whether wc is a wide-character code representing a character of class "lower" in the program's current locale.
iswdigit(wc): Tests whether wc is a wide-character code representing a character of class "digit" in the program's current locale.
iswxdigit(wc): Tests whether wc is a wide-character code representing a character of class "xdigit" in the program's current locale.
iswalnum(wc): Tests whether wc is a wide-character code representing a character of class "alpha" or "digit" in the program's current locale.
iswspace(wc): Tests whether wc is a wide-character code representing a character of class "space" in the program's current locale.
iswpunct(wc): Tests whether wc is a wide-character code representing a character of class "punct" in the program's current locale.
iswprint(wc): Tests whether wc is a wide-character code representing a character of class "print" in the program's current locale.
iswgraph(wc): Tests whether wc is a wide-character code representing a character of class "graph" in the program's current locale.
iswcntrl(wc): Tests whether wc is a wide-character code representing a character of class "cntrl" in the program's current locale.
iswascii(wc): Tests whether wc is a wide-character code representing an ASCII character.
isphonogram(wc): Tests whether wc is a wide-character code representing a phonetic language character, excluding ASCII characters.
isideogram(wc): Tests whether wc is a wide-character code representing an ideographic language character, excluding ASCII characters.
isenglish(wc): Tests whether wc is a wide-character code representing an English language character, excluding ASCII characters.
isnumber(wc): Tests whether wc is a wide-character code representing digit [0-9], excluding ASCII characters.
isspecial(wc): Tests whether wc is a wide-character code representing a special language character, excluding ASCII characters.
