WIDE CHARACTER CLASSIFICATION

These functions classify Process Code characters ( wchar_t ) from the primary and supplementary codesets by table lookup. Each is a predicate returning nonzero for true, zero for false. The lookup table, generated by wchrtbl(), contains values for both ASCII and supplementary codesets.

iswalpha(c)

c is a Latin alphabet Process Code character, from either the primary or supplementary codesets.

iswupper(c)

c is an upper case Latin alphabet Process Code character, from either the primary or supplementary codesets.

iswlower(c)

c is a lower case Latin alphabet Process Code character, from either the primary or supplementary codesets.

iswdigit(c)

c is a Process Code digit [0-9], from either the primary or supplementary codesets.

iswxdigit(c)

c is an ASCII hexadecimal Process Code digit [0-9], [A-F], or [a-f].

iswalnum(c)

c is a Process Code Latin letter or a digit, from either the primary or supplementary codesets.

iswspace(c)

c is a Process Code space, tab, carriage return, newline, vertical tab, or formfeed, from either the primary or supplementary codesets.

iswpunct(c)

c is an ASCII Process Code punctuation character (neither control nor alphanumeric).

iswprint(c)

c is a Process Code printing character, from either the primary or supplementary codesets. It includes the space character.

iswgraph(c)

c is a Process Code visible graphic character, from the primary or supplementary codesets. It does not include the space character.

iswcntrl(c)

c is a Process Code ASCII delete character or ordinary control character, or a control character from a supplementary codeset.

iswascii(c)

c is a Process Code ASCII character.

isphonogram(c)

c is a Process Code phonetic language character from a supplementary codeset.

isideogram(c)

c is a Process Code ideographic language character from a supplementary codeset.

isenglish(c)

c is a Process Code English language character from a supplementary codeset.

isnumber(c)

c is a Process Code digit [0-9] from a supplementary codeset.

isspecial(c)

c is a Process Code special language character from a supplementary codeset.
