TRAD_SYNOPSIS
|

DESCRIPTION
|
|
|
|
<<iswprint>> is a function which classifies wide-character values that
|
|
|
|
are printable.
|
|
|
|
|
2017-10-07 00:16:47 +00:00
|
|
|
<<iswprint_l>> is like <<iswprint>> but performs the check based on the
|
|
|
|
locale specified by the locale object locale. If <[locale]> is
|
|
|
|
LC_GLOBAL_LOCALE or not a valid locale object, the behaviour is undefined.
