The iissuuppppeerr() function tests for any uppercase letter or any of an im
plementationdefined set of characters for which none of iscntrl(3),
isdigit(3), ispunct(3), or isspace(3) is true. In the _`_`_C_'_' locale,
iissuuppppeerr() returns true only for the characters defined as uppercase let
ters.

The iissuuppppeerr() macro returns zero if the character tests false and returns
nonzero if the character tests true.
