| "blank" | blank character | iswblank |
| "cntrl" | control character | iswcntrl |
| "digit" | decimal digit character | iswdigit |
| "graph" | character with graphical representation | iswgraph |
| "lower" | lowercase letter character | iswlower |
| "print" | printable character | iswprint |
| "punct" | punctuation character | iswpunct |
| "space" | white-space character | iswspace |
| "upper" | uppercase letter character | iswupper |

The value returned by this function depends on the LC_CTYPE locale category selected.
