NAME
iswprint - test for a printable wide-character code
SYNOPSIS
#include <wctype.h>
int iswprint(wint_t wc);
DESCRIPTION
The iswprint() function shall test whether wc is a wide-character code
representing a character of class print in the program’s current
locale; see the Base Definitions volume of IEEE Std 1003.1-2001,
Chapter 7, Locale.
The wc argument is a wint_t, the value of which the application shall
ensure is a wide-character code corresponding to a valid character in
the current locale, or equal to the value of the macro WEOF. If the
argument has any other value, the behavior is undefined.
RETURN VALUE
The iswprint() function shall return non-zero if wc is a printable
wide-character code; otherwise, it shall return 0.
ERRORS
No errors are defined.
The following sections are informative.
EXAMPLES
None.
APPLICATION USAGE
To ensure applications portability, especially across natural
languages, only this function and those listed in the SEE ALSO section
should be used for classification of wide-character codes.
RATIONALE
None.
FUTURE DIRECTIONS
None.
