NAME



islower

 - lower-case character test

LIBRARY

Lb libc

SYNOPSIS

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

DESCRIPTION

The islower ();
function tests for any lower-case letters. 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):

"141 ``a'' 142 ``b'' 143 ``c'' 144 ``d'' 145 ``e''"
"146 ``f'' 147 ``g'' 150 ``h'' 151 ``i'' 152 ``j''"
"153 ``k'' 154 ``l'' 155 ``m'' 156 ``n'' 157 ``o''"
"160 ``p'' 161 ``q'' 162 ``r'' 163 ``s'' 164 ``t''"
"165 ``u'' 166 ``v'' 167 ``w'' 170 ``x'' 171 ``y''"
"172 ``z''"

RETURN VALUES

The islower ();
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 iswlower ();
function should be used instead.
