Standard C Library (libc, -lc) SYNOPSIS
#include <wctype.h> int iswalnum(wint_t wc); int iswalpha(wint_t wc); int iswblank(wint_t wc); int iswcntrl(wint_t wc); int iswdigit(wint_t wc); int iswgraph(wint_t wc); int iswlower(wint_t wc); int iswprint(wint_t wc); int iswpunct(wint_t wc); int iswspace(wint_t wc); int iswupper(wint_t wc); int iswxdigit(wint_t wc); DESCRIPTION
The functions are character classification utility functions, for use with wide characters (wchar_t or wint_t). See the description of sin- glebyte classification functions, like isalnum(3), for details. RETURN VALUES
The functions return zero if the character tests false and return non-zero if the character tests true. SEE ALSO
