iswspace manual

iswspace - test for whitespace wide character

The  iswspace()  function  is the wide-character equivalent of the iss-
pace(3) function.  It tests whether wc is a wide character belonging to
the wide-character class `space`.

The  wide-character  class  `space` is disjoint from the wide-character
class `graph` and therefore also disjoint from its subclasses  `alnum`,
`alpha`, `upper`, `lower`, `digit`, `xdigit`, `punct`.

The  wide-character  class  `space`  contains  the wide-character class
`blank`.

The wide-character class `space` always contains  at  least  the  space
character and the control characters `\f`, `\n`, `\r`, `\t`, `\v`.

Return Value

The iswspace() function returns nonzero if wc is a wide character belonging to the wide-character class space.
Otherwise, it returns zero.

Notes

The behavior of iswspace() depends on the LC_CTYPE category of the current locale.
