NAME
isupper - upper-case character test
SYNOPSIS
#include <ctype.h>
int
isupper(int c);
DESCRIPTION
The isupper() function tests for any upper-case letter or any of an
implementation-defined set of characters for which none of iscntrl(3),
isdigit(3), ispunct(3), or isspace(3) is true. In the C locale,
isupper() returns true only for the characters defined as upper-case
letters.
RETURN VALUES
The isupper() macro returns zero if the character tests false or non-zero
if the character tests true.

STANDARDS
The isupper() function conforms to ANSI X3.159-1989 (``ANSI C'').
