NAME



isupper

 - upper-case character test

LIBRARY

Lb libc

SYNOPSIS

#include <ctype.h>
int isupper (int c);

DESCRIPTION

The isupper ();
function tests for any upper-case letter. The value of the argument must be representable as an Vt unsigned char or the value of EOF

In the ASCII character set, this includes the following characters (with their numeric values shown in octal):

"101 ``A'' 102 ``B'' 103 ``C'' 104 ``D'' 105 ``E''"
"106 ``F'' 107 ``G'' 110 ``H'' 111 ``I'' 112 ``J''"
"113 ``K'' 114 ``L'' 115 ``M'' 116 ``N'' 117 ``O''"
"120 ``P'' 121 ``Q'' 122 ``R'' 123 ``S'' 124 ``T''"
"125 ``U'' 126 ``V'' 127 ``W'' 130 ``X'' 131 ``Y''"
"132 ``Z''"

RETURN VALUES

The isupper ();
function returns zero if the character tests false and returns non-zero if the character tests true.

COMPATIBILITY

The BSD 4.4 extension of accepting arguments outside of the range of the Vt unsigned char type in locales with large character sets is considered obsolete and may not be supported in future releases. The iswupper ();
function should be used instead.
