- The iissaallpphhaa() function tests for any character for which isupper(3) or
- islower(3) is true and for which none of iscntrl(3), isdigit(3),
- ispunct(3), or isspace(3) is true. In the _`_`_C_'_' locale, iissaallpphhaa() re-
- turns true only for the characters for which isupper(3) or islower(3) is
- true.

- The iissaallpphhaa() macro returns zero if the character tests false and returns
- non-zero if the character tests true.
