There are twelve strings that are reserved for the standard character classes:
| "alnum" | "alpha" | "blank" |
| "cntrl" | "digit" | "graph" |
| "lower" | "print" | "punct" |
| "space" | "upper" | "xdigit" |
In the table below, the functions in the left column are equivalent to the functions in the right column.
| iswalnum(wc) | iswctype(wc, wctype("alnum")) |
| iswalpha(wc) | iswctype(wc, wctype("alpha")) |
| iswcntrl(wc) | iswctype(wc, wctype("cntrl")) |
| iswdigit( wc) | iswctype(wc, wctype("digit")) |
| iswgraph(wc) | iswctype(wc, wctype("graph")) |
| iswlower(wc) | iswctype(wc, wctype("lower")) |
| iswprint(wc) | iswctype(wc, wctype("print")) |
| iswpunct(wc) | iswctype( wc, wctype("punct")) |
| iswspace(wc) | iswctype(wc, wctype("space")) |
| iswupper(wc) | iswctype(wc, wctype("upper")) |
| iswxdigit(wc) | iswctype(wc, wctype("xdigit")) |
The call
iswctype(wc, wctype("blank"))
does not have an equivalent isw*() function.
