.SH DESCRIPTION |
|
15 |
.LP
|
|
16 |
The \fIiswupper\fP() function shall test whether \fIwc\fP is a wide-character |
|
17 |
code representing a character of class |
|
18 |
\fBupper\fP in the program's current locale; see the Base Definitions |
|
19 |
volume of IEEE\ Std\ 1003.1-2001, Chapter 7, Locale. |
|
20 |
.LP
|
|
21 |
The \fIwc\fP argument is a \fBwint_t\fP, the value of which the application |
|
22 |
shall ensure is a wide-character code |
|
23 |
corresponding to a valid character in the current locale, or equal |
|
24 |
to the value of the macro WEOF. If the argument has any other |
|
25 |
value, the behavior is undefined. |
|
26 |
.SH RETURN VALUE |
|
27 |
.LP
|
|
28 |
The \fIiswupper\fP() function shall return non-zero if \fIwc\fP is |
|
29 |
an uppercase letter wide-character code; otherwise, it |
|
30 |
shall return 0. |

|
42 |
only this function and those listed in the SEE ALSO |
|
