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 or the locale specified by loc.

The functions iswalpha_l(), iswideogram_l(), iswnumber_l(), iswphonogram_l(), iswspecial_l(), iswalnum_l(), iswascii_l(), iswblank_l(), iswcntrl_l(), iswdigit_l(), iswgraph_l(), iswlower_l(), iswprint_l(), iswpunct_l(), iswspace_l(), iswupper_l(), all behave identically to their counterparts without the '_l' suffix, but instead of operating on the current locale, they operate on the locale specified by loc.

The functions, iswideogram(), iswnumber(), iswphonogram(), iswspecial(), and iswhexnumber(), are respectively identical to isideogram(), isnumber(), isphonogram(), isspecial(), iswxdigit() respectively. They are provided for compatability purposes.

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.

isenglish(wc)

Tests whether wc is a wide-character code representing an English language character, excluding ASCII characters.

isideogram(wc)

Tests whether wc is a wide-character code representing an ideographic language character, excluding ASCII characters.

isnumber(wc)

Tests whether wc is a wide-character code representing digit [0-9], excluding ASCII characters.

isphonogram(wc)

Tests whether wc is a wide-character code representing a phonetic language character, excluding ASCII characters.

isspecial(wc)

Tests whether wc is a wide-character code representing a special language character, excluding ASCII characters.

iswalnum(wc)

Tests whether wc is a wide-character code representing a character of class "alpha" or "digit" in the program's current locale.

iswascii(wc)

Tests whether wc is a wide-character code representing an ASCII character.

iswblank(wc)

Tests whether wc is a wide-character code representing a character of class "blank" in the program's current locale. This function is not available to applications conforming to standards prior to SUSv3. See standards(5).

iswlower(wc)

Tests whether wc is a wide-character code representing a character of class "lower" 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.

iswdigit(wc)

Tests whether wc is a wide-character code representing a character of class "digit" 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.

iswprint(wc)

Tests whether wc is a wide-character code representing a character of class "print" 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.

iswspace(wc)

Tests whether wc is a wide-character code representing a character of class "space" 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.

iswxdigit(wc)

Tests whether wc is a wide-character code representing a character of class "xdigit" in the program's current locale.
