Return Value
isprint returns a nonzero value if c is a printable character, including the space character (0x20 – 0x7E). iswprint returns a nonzero value if c is a printable wide character, including the space wide character. Each of these routines returns 0 if c does not satisfy the test condition.
The result of the test condition for the isprint function depends on the LC_CTYPE category setting of the current locale; see setlocale for more information. For iswprint, the result of the test condition is independent of locale.
