.SH DESCRIPTION |
|
15 |
.LP
|
|
16 |
The \fIisprint\fP() function shall test whether \fIc\fP is a character |
|
17 |
of class \fBprint\fP in the program's current locale; |
|
18 |
see the Base Definitions volume of IEEE\ Std\ 1003.1-2001, Chapter |
|
19 |
7, Locale. |
|
20 |
.LP
|
|
21 |
The \fIc\fP argument is an \fBint\fP, the value of which the application |
|
22 |
shall ensure is a character representable as an |
|
23 |
\fBunsigned char\fP or equal to the value of the macro EOF. If the |
|
24 |
argument has any other value, the behavior is undefined. |
|
25 |
.SH RETURN VALUE |
|
26 |
.LP
|
|
27 |
The \fIisprint\fP() function shall return non-zero if \fIc\fP is a |
|
28 |
printable character; otherwise, it shall return 0. |
