int iswalpha(int c);

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.
